Winning is finding joy in things.#

Richard Feynman

I started going on regular long hikes in the mountains around Seattle with a group of boys when I was about thirteen. We met in the Boy Scouts. We did a lot of hiking and camping with the troop, but soon we formed our own little group to go on our own adventures—we called it exploration. We wanted more freedom and adventure than the Scouts offered.

Usually, there were five of us—Mike, Rocky, Reilly, Danny, and me. Mike was the leader; he was a few years older than the rest of us and had more outdoor experience. Over the next three years, we hiked hundreds of miles together. We traversed the Olympic National Forest in the eastern part of Seattle and the Glacier Peak Wilderness in the northeast, hiking along the Pacific coast. We often hiked for seven days or more, relying only on topographical maps to navigate through the wilderness and rocky beaches, trying to time our runs with the tides. During school breaks, we would go on long trips, hiking and camping regardless of the weather, which in the Pacific Northwest often meant spending a week in wet, itchy military surplus wool pants and with cracked toes. We did not engage in technical climbing. No ropes or harnesses or vertical rock faces. Just long, hard hikes. It wasn't dangerous, except that we were boys, deep in the mountains, far from help, and before the advent of cell phones.

Over time, we became a confident, tightly-knit team. After a full day of hiking, we would decide on a camping spot, and without much need for words, we would each take on our tasks. Mike and Rocky would probably set up the roof tarp for the night. Danny would gather dry firewood from the bushes, while Reilly and I would strike a match and light some sticks to start a campfire for the night.

Then we would eat. Cheap food packed in our backpacks was enough to sustain us on our journey. Nothing tasted better. For dinner, we would chop up a can of luncheon meat and mix it with hamburger helper or a bag of beef stroganoff. In the mornings, we might drink Corning instant breakfast powder or a powder that turned into scrambled eggs when mixed with water, at least that’s what the package said. My favorite breakfast food was Oscar Mayer smoked sausage, a “all-meat” sausage that is now extinct. We cooked most of our food in a frying pan, and we ate from the empty #10 coffee cans each person carried. These cans served as our buckets, stew pots, and oatmeal bowls. I don’t know who among us invented the hot raspberry drink. It wasn’t a great culinary innovation: just add instant jelly powder to hot water. It served as both dessert and a sugar boost for the morning before a day of hiking.

That said,

In the 1970s, the attitude toward parenting was more relaxed than it is today. Kids generally had more freedom. By the time I was a teenager, my parents had accepted my differences from many of my peers and had come to terms with the fact that I needed to carve my own path in the world. This acceptance had been hard—especially for my mother—but it would become a key factor in shaping my future.

Looking back now, I’m sure each of us was looking for something beyond friendship and a sense of accomplishment on those trips. We were at an age where kids test their limits and try on different identities, sometimes feeling a yearning for something larger, even transcendent. I began to feel a strong desire to figure out what my path in life would be. I wasn’t sure which direction it would take, but it definitely needed to be something interesting and meaningful.

During those years, I spent a lot of time with a different group of boys. Kent, Paul, Rick, and I all attended the same school—Lakeside, which had set up a way for students to connect to a large computer via telephone lines. At that time, it was very rare for teenagers to have access to computers. The four of us loved that machine, spending all our free time writing more complex programs and exploring what we could do with this electronic device.

On the surface, the differences between hiking and programming seemed vast. But they both felt like an adventure. With two groups of friends, I was exploring new worlds, going to places that even most adults couldn’t reach. Like hiking, programming suited me because it allowed me to define my own standards of success and seemed limitless, unbound by how fast I could run or how far I could throw. The logic, focus, and endurance required to write long, complex programs came naturally to me. Unlike hiking, among that group of friends, I was the leader.

As my sophomore year was coming to an end,

• In June 1971, Mike called me to arrange our next trip: a 50-mile hike in the Olympic Mountains. The route he chose was called the News Survey Trail, an area explored by a group sponsored by a newspaper in 1890. Was he referring to that trip that nearly starved us and left our clothes rotting on our backs? Yes, but that was a long time ago, he said.

• Eighty years later, it was still a tough hike; there had been a lot of snow that year, so it was a particularly daunting challenge. But since the others—Rocky, Reilly, and Danny—were all ready, I would never back down. And a young scout named Chip was eager to join. I had to go.

• At that time, someone had lent Lakeside a PDP-8 computer made by DEC (Digital Equipment Corp.). This was in 1971, when I was deeply immersed in the budding world of computers and had never seen anything like it. Until then, my friends and I had only used those massive mainframe computers shared with others. We usually connected to them via telephone lines, otherwise they were locked in a separate room. But the PDP-8 was designed to be used directly by one person and was small enough to fit on a desk beside you. It was probably the closest thing to a personal computer at the time, even though it weighed 80 pounds and cost $8,500. To challenge myself, I decided to try to write a version of the BASIC programming language for this new computer.

Three and a half years later, I was a sophomore in college, still uncertain about my path in life. Paul was one of my friends from Lakeside, and he suddenly burst into my dorm room with news about a groundbreaking computer. I knew we could write a version of BASIC for it; we were already ahead of the game. The first thing I did was recall that painful experience on the Lo Pass Trail, retrieving from memory the evaluator code I had written. I typed it into the computer, thus planting the seeds for one of the largest companies in the world and launching a new industry.

Time would tell there would be a big company. Over time, there would be billions of computers using software programs, with lines of code stretching into the millions. There would be wealth and competition, along with constant worries about how to stay at the forefront of the technological revolution.

Before that, there was a deck of cards and a goal: to beat my grandmother.

In my family, the quickest way to win affection was to excel at games, especially card games. If you were confident in Rummy, Bridge, or Canasta, we would respect you, which made my grandmother, Adele Thompson, a household legend. As a child, I often heard the saying, “Grandma is the best at card games.”

Gami grew up in rural Washington state in the railroad town of Enkirk. It was less than fifty miles from Seattle, but in the year she was born, 1902, it was another world. Her father was a railroad telegrapher, and her mother, Ida Thompson—whom we called Lala—eventually made a decent income baking cakes and selling war bonds at the local lumber mill. Lala also played a lot of bridge. Her partners and opponents were the socialites of the town, the wives of bankers and lumber mill owners. These people might have had more money or higher social status, but Lala made up some of the gap by easily defeating them at card games. This talent was passed down to Gami and, to some extent, to her only daughter.

My immersion into this family culture began early. When I was still in diapers, Lala started calling me “Trey,” which is slang for three in poker. This was because I was the third generation of Bill Gates alive in the family, after my dad and grandfather. (Actually, I’m the fourth generation, but my dad chose to call himself “junior,” so I was called Bill Gates III.) Gami had me playing “Fish” by the time I was five. Over the next few years, we would play thousands of hands. We had a lot of fun, both for entertainment and to pass the time. But my grandmother also played to win, and she always managed to do so.

I was fascinated by her mastery at the time. How did she get so good? Was she born that way? Was she devout, perhaps a gift from God? For a long time, I had no answers. All I knew was that every time we played, she would win. No matter what game, no matter how hard I tried.

When Christian Science rapidly expanded to the West Coast in the early 20th century, both sides of my parents' families became devout followers. I believe my mother’s parents drew strength from Christian Science, embracing the belief that a person’s true identity lies in spirituality rather than materiality. They were strict adherents. Because Christian Scientists do not track age, Grandma never celebrated her birthday and never revealed her age or even the year she was born. Despite her own beliefs, Grandma never imposed her views on others. My mom did not adhere to this faith, nor did our family. Grandma never tried to persuade us to take another path.

Her beliefs may have played a role in shaping her into an extremely principled person. Even then, I could understand that Gami followed a strict personal code of fairness, justice, and integrity. Living a meaningful life meant living simply, giving time and money to others, and most importantly, using your mind—staying connected to the world. She never lost her temper, never spread gossip or criticism. She wouldn’t play tricks. She was often the smartest person in the room, but she would carefully nurture others to shine. She was essentially a shy person, but with a confidence that manifested as a Zen-like calm.

Two months before my fifth birthday, my grandfather, J.W. Maxwell Jr., died of cancer. He was only fifty-nine. Following his Christian Science beliefs, he refused modern medical intervention. His last years were filled with pain, and Gami, as his caregiver, suffered as well. I later learned that Grandpa believed his suffering was in some way due to Gami’s actions, some unknown sin in the eyes of God, now punishing him. Nevertheless, she remained by his side with calmness, supporting him until the end of his life. One of my deepest childhood memories is of my parents not allowing me to attend his funeral. I was barely aware of what was happening, only knowing that my mother, father, and sister went to see him one last time while I stayed home with a babysitter. A year later, my aunt Lala died at Gami’s house.

From then on, my aunt poured all her love and attention into me and my sister, Kristi, and later my sister Libby joined us. She was with us during our formative years and had a profound impact on our future development. Before I could even hold a book, she read stories to me, and for many years afterward, she told me classic tales like “Gone with the Wind,” “The Adventures of Tom Sawyer,” and “Charlotte’s Web.” After my grandfather’s death, my aunt began teaching me to read on my own, helping me sound out words in “The Nine Friendly Dogs,” “What a Beautiful Day,” and other books around the house. After we finished all those books, she would drive me to the Northeast Seattle library to borrow more. I knew she read a lot and seemed knowledgeable in various fields.

My grandparents built a large house in the upscale neighborhood of Windermere in Seattle, big enough to accommodate grandchildren and family gatherings. Grandma continued to live there after Grandpa passed away. Some weekends, Kristi and I would spend the night there, taking turns sleeping in Grandma’s room. The other would sleep in a nearby bedroom, where everything—from the walls to the curtains—was light blue. The shadows of streetlights and passing cars would cast shapes in that blue room. I felt scared sleeping there and was always glad when it was my turn to sleep in Grandma’s room.

Those weekend visits were special. Her house was only a few miles from ours, but the time spent there felt like a vacation. She had a swimming pool and a mini-golf course built by my grandfather, and we often played in the yard next door. She also allowed us to watch television, which was a strictly controlled activity in our own home. Gami was willing to try anything; thanks to her, my sisters and I became avid gamers, turning anything—like Monopoly, Risk, or Concentration—into a competitive sport. We would buy two puzzles and race to see who could finish first. But we knew her preferences. Most nights after dinner, she would deal the cards and then proceed to defeat us soundly.

We played Cat and Mouse, Goldfish, Hearts, and my favorite game, Seven Points. We also played her favorite, a complex Goldfish game she called “Coast Guard Hearts.” We played a bit of bridge. We went through a book by Dr. Howell in order, playing various popular and less popular games, including Hearts War.

Meanwhile, I was studying her. In computer science, there’s something called a state machine, which is part of a program that receives input and takes the best action based on the state of a series of conditions. My grandmother had a finely-tuned card-playing state machine; her mental algorithm worked through probabilities, decision trees, and game theory systematically. I might not have been able to articulate these concepts clearly, but gradually I began to intuit them. I noticed that even in unique moments during games—a set of possible moves and probabilities she might never have seen before—she would usually choose the best action. If she lost a good card at some point, I would later see her sacrifice it for some reason: to win at a later moment.

We played and played, and I lost and lost. But I was observing, always improving. All along, Gami was gently encouraging me. “Think smart, Trey. Think smart.” The implication was that if I used my brain and stayed focused, I could find the right card to play. I could win.

One day I did.

I was born on October 28, 1955, the second of three children. My sister Kristi was born in 1954, twenty-one months older than me; my sister Libby was born nearly ten years later. As a baby, I was called the “happy boy” for always showing a bright smile. Not that I never cried, but the joy I exhibited seemed to overshadow all other emotions. Another notable trait from my early years could be described as excessive energy. I rocked. Initially, it was on a rubber toy horse for hours on end. As I grew older, I didn’t abandon the habit, rocking while sitting, standing, or whenever I felt the need to think deeply. Rocking was like a metronome for my brain. It still is.

My parents realized early on that my thinking rhythm was different from other kids. Kristi was an obedient child, easy to play with other kids, and excelled academically from the start. I was nothing of the sort. My mom worried about me and warned the teachers at Acorn Kindergarten to have certain expectations. By the end of my first year in kindergarten, the principal wrote, “His mother has prepared him well, as she seems to feel he contrasts sharply with his sister. We completely agree with her conclusion, as he seems determined to make us feel his indifference to every aspect of school life. He does not know or care how to cut, put on his coat, and is perfectly happy to ignore it.” (Interestingly, one of Kristi’s early memories of me includes always having to get me into my coat and then lying me down on the floor so she could zip it up.)

In second grade at Acorn, I was a “recently exhibiting aggressive, rebellious behavior” child, a four-year-old who loved to sing alone and go on imaginary journeys. I fought with other kids and “felt frustrated and unhappy most of the time,” the principal reported. Fortunately, my teachers were excited about my long-term plans: “We feel very accepted by him because he includes us in his planned moon landing,” they wrote. (I was years ahead of Kennedy.)

The hints that educators and my parents noticed when I was very young foreshadowed what was to come. I would channel my strong desire to solve Gami’s card skill puzzles into an interest in anything that caught my attention, ignoring the mundane. The things that attracted me included reading, math, and immersing myself in my thoughts. The things that bored me included the routines of daily life and school, handwriting, art, and sports. Also, almost everything my mother told me to do.

My father was known as a gentle giant, standing six feet seven inches tall, with a calm and polite demeanor you might not expect from someone who was often the tallest person in the room. He dealt with people directly and purposefully, a trait that shaped his image and suited his profession as a lawyer (later the first head of our charitable foundation) who advised businesses and boards. While polite, he was not shy about making his demands. As a college student, what he wanted was a dance partner.

In the fall of 1946, he was part of a wave of veterans participating in the massive G.I. Bill, a generous government program that allowed millions to receive an education they might not otherwise afford. To my father, the only downside was that the number of men on the Washington University campus far exceeded the number of women. This meant there were few opportunities to find a dance partner. At some point, he asked a friend for help. Her name was Mary Maxwell.

My father always claimed that his request for an introduction was not a sly way to get my mom to date him. But that’s exactly what it was. He said, “Come on, let’s go out.” Then, the story goes, two years later they were married.

I have always loved hearing this story because it perfectly showcases my parents’ personalities. My dad: cautious and unapologetically practical, sometimes even in matters of the heart. My mom: sociable and unhesitating in pursuing what she wanted. It’s a clever story, a distillation of the whole narrative that highlights not just the differences in appearance but ultimately will influence the kind of person I would become.

My objective conclusion about our relationship is that we had a lot in common, which is a very good thing. We had similar desires for social and family life. I think we both wanted a very close marriage, meaning we hoped the two of us would become one. Although our social and family backgrounds were different, I think we could understand the issues that arose from that because, as individuals, we were quite similar. We both liked to grapple with ideas, constantly thinking and learning… We both yearned for the same thing—to achieve success in the world as much as possible through honest and fair means. While we placed a high value on success, we would never consider it worth it to be unfair at the expense of another person. We wanted our children to have the same fundamental values. Perhaps our “means” would differ, but I tend to think we could present a consistent stance that would complement both viewpoints… You know, Bill, if you truly love me, I would do anything for you.

My mother’s confidence and ambition likely came half from the Maxwell family and half from Gami. Besides being good at cards, Gami was an excellent student among high school graduates, a basketball prodigy, and well-read, pursuing a broader life away from her hometown. She met my grandfather at the University of Washington. In 1946, my mom followed in her footsteps to the University of Washington, receiving full support from two ambitious parents and the general expectation from the family that she would excel.

Two years later, life in Bremerton, better job prospects, and a more vibrant life drew them back to Seattle, and within months of my birth, we moved into a newly built house in a place called Winridge in North Seattle, where there was an elementary school, a children’s park, and a library within walking distance. The entire community was still under construction when we arrived. I have a film my dad shot after we moved: you can see a lawn that hasn’t been seeded yet, and my sister riding her tricycle on a sidewalk that looks almost liquid clean. Across the street is the outline of a wooden house that is unfinished. Watching that film, I marvel at how new everything was, as if the entire community had just been built for kids like us.

There was a loud bang, and then the house shook. My mom had just said goodbye to Kristi, me, and the babysitter; she was about to head out to meet my dad for dinner. When the house shook, she froze, her hand still on the doorknob. At that moment, we saw through the backyard window the roof of the garage fly over our house, crash into the backyard, and knock down the neighbor’s fence.

My mother guided us into the basement, where we huddled near a pile of canned food and other nuclear attack supplies. In 1962, a nuclear bomb seemed more likely than the tornado that was disrupting that Friday night: it was the first recorded tornado in Seattle. It formed in our View Ridge neighborhood, landed on our street, then crossed our yard, continuing across Lake Washington, where it pulled up a hundred-foot-high column of water. The whole thing was over in fifteen minutes. Miraculously, no one was injured. Aside from uprooted trees and broken windows, most of the damage to our community was limited to our garage. The Seattle Post-Intelligencer sent a reporter and photographer. My mother pasted the accompanying photo (of a neighborhood child standing on the crushed structure) in her scrapbook along with other childhood memories.

My dad wanted to throw a barbecue party, inviting friends over to see the pile of wood scraps, metal pipes, and asphalt shingles that used to be our garage. No way, my mom said. She was still shaken. Who knows what would have happened if she had opened that door a moment earlier, and we would have been affected too. And no decent family would celebrate such a thing. It would be in poor taste. It didn’t align with my mom’s view of how the Gates family should present itself.

Kristi and I (and later Libby) were part of a large group of children born in the post-World War II era of prosperity and optimism. It was the height of the Cold War, and the civil rights movement was underway. A few weeks after the tornado, Kennedy and Khrushchev clashed over Soviet missiles in Cuba. On the last day of that crisis, when the world avoided nuclear catastrophe, I was playing with my seventh birthday gift in our living room. Within a year, a quarter of a million people marched on Washington, and Martin Luther King said he dreamed that one day our nation would become a place where everyone was equal.

The awareness of these historical events began to crystallize in my mind, just a few names and words I heard while my parents watched CBS Evening News. In school, teachers showed us chilling films about Hiroshima and mushroom clouds. We practiced ducking and covering. But for kids living in View Ridge, that larger world felt abstract. A destroyed garage was probably the most dramatic event in our lives. Families like ours had a strong sense of confidence. Our parents and all the parents around us had lived through the Great Depression and World War II. Anyone could see that America was thriving.

Like other places across the country, Seattle was rapidly expanding into the suburbs. Fields and forests were cleared to build homes and shopping centers. This transformation had begun in our city during the war, with the local company Boeing becoming a major manufacturer of fighter planes. When I was born, Boeing had just launched its first viable commercial airliner, and in the coming years, the act of flying would go from mysterious to commonplace.

From my bedroom window, I could hear the sounds of baseball bats hitting balls from the neighbors’ houses across the View Ridge field. When I started attending View Ridge Elementary in 1960, the school had just added a new wing to accommodate over a thousand students; soon, the city would need to build a second elementary school nearby. On a hill ten blocks from our house, the Northeast branch of the Seattle Public Library had the largest selection of children’s books in the city’s library system. When the library opened a year before I was born, a line of kids stretched from the door all the way down the street. It became a kind of club throughout my teenage years, for a long time my favorite place in the world.

It was a community of families made up of businessmen, doctors, engineers, and lawyers, many of whom were World War II veterans who found a way to go to college and live better lives in North Seattle thanks to the G.I. Bill. It was a white, middle-class community. If I had been born Black in Seattle in 1955, I wouldn’t have lived in Winridge. Our community and others around it had enacted racial covenants in the 1930s that prohibited “non-whites” from living in the houses there (except for domestic help). Although these terrible restrictions were technically terminated by the Supreme Court in 1948, Seattle continued to segregate for a long time, with people of color forced to live primarily in the industrial south of the city.

In 1962, when I was in first and second grade, I often walked up a small hill with Kristi to Winridge Elementary, where my sister set the standard for the expectations teachers had of me. Kristi was a rule-follower. In the backseat of the car, she constantly monitored the speedometer, and any time my dad sped, she would remind him. At school, she was a serious student, friendly to teachers, completed her assignments on time, and most importantly, excelled academically.

Unlike others, as my mom had warned my preschool teachers. In the early years of elementary school, I read a lot of books alone at home. I taught myself how to learn, and I loved the feeling of quickly absorbing new knowledge and entertaining myself with chapter books. However, at school, I felt slow. I found it hard to maintain interest in what we were learning; my thoughts often wandered. When something caught my attention, I might suddenly stand up, wave my hand wildly, or shout out answers. I didn’t mean to create chaos; my mind just easily slipped into a state of unrestrained excitement. At the same time, I felt out of sync with the other kids. My late October birthday meant I was younger than most of my classmates, and I really looked it. I was small and thin, with a very high-pitched voice. I was shy in front of other kids. And I had a rocking habit.

The days went on in the same way, year after year. On Christmas Eve, my mom would prepare matching pajamas for everyone in the family. The next morning, we would all gather in the hallway in our new pajamas and then take turns walking into the living room in age order. (Doing things in age order was a strict family tradition.) Then, in descending order, we would open our stockings. We always knew what we would find: an orange and a silver dollar for the kids, and for my mom, always a bouquet of red carnations from my dad. Then, even with a pile of gifts to open, we would pause for breakfast first: scrambled eggs and ham Danish from the nearby bakery. Finally, we would open the presents. After Kristi, I would open one with everyone, and then we would cycle through, starting with Grandma, until the youngest was done. The gifts tended to be practical and fun, never expensive. You could always find things like socks and shirts, maybe the latest bestseller.

As the holidays drew to a close, with the last decoration packed away and the final thank-you note sent out, my mom would pull out pen and paper to start preparing for the next Christmas. Even occasionally when my sisters and I would roll our eyes at these traditions—staying up late wrapping gifts while still in our pajamas—if any one of them were skipped, it would feel like a loss. Christmas remains one of my sisters’ and my favorite memories.

A few days after I finished second grade, my mom and grandma packed me and my sister up, and we drove off to begin our first big vacation. Kristi and I always called it the Disney trip, but it was much more than that. For my mom, it meant a thousand opportunities for her children to learn during the long journey ahead.

On a June morning in 1963, we set off right on time, at 8:15—exactly as my mom had recorded. The first stop of the entire trip was Los Angeles, which would take four days. That week, my dad had to work, and he would fly to meet us when we arrived at Disneyland, then drive back home with us.

My mom had recently bought the most advanced typing technology of the time. Her IBM Selectric used a metal ball the size of a golf ball that could provide different fonts and styles of writing. You could switch it out for the font and style you wanted, even choosing cursive, which I thought was the coolest thing. Before the trip, my mom prepared a travel journal for me and my sister, with two pages for each day where we would record what we saw and learned. She provided us with headings in mechanical cursive, allowing us to list the cities we traveled to and the approximate miles we drove each day. Below, she printed categories to fill in. It looked something like this:

At the bottom, she set up a section for writing a description of the day’s journey. For this task, we would not lack for data. My mom’s previous energy had set a detailed itinerary for each day, leading us through two state capitols, Oregon’s lava forest, several universities, the Golden Gate Bridge, Hearst Castle, San Quentin Prison, the San Diego Zoo, a beeswax demonstration, and a host of other stops.

While my mom drove, Grandma read us a novel about Man O’ War, a thoroughbred that broke speed and endurance records and was one of the most winning horses in history. While listening, my sister and I kept an eye out the window for things to note down in our travel journals: apple orchards, adobe buildings, trucks loaded with Douglas fir logs, oil wells. Each night at the motel, Kristi would record what we had seen by category. She wrote carefully, knowing my mom would later correct her grammar and spelling with a red pen. I would jot down my extra observations in a smaller notebook, trying to write them as neatly as possible.

When my dad met us in Los Angeles, we told him about the amazing horse we had just finished learning about, one bred and raised to win. At some point in the future, I would feel that my mom was also pursuing a similar mission, alongside her children.

One day, Mrs. Rona took me down the hall to the library and told the librarian I needed a challenge. Was there a task she could give me?

The library was small, typical of what you would find in a 1960s elementary school library, meaning there were no computers, just books and periodicals. There were plenty of National Geographic magazines, popular series like “Black Stallion,” a set of old encyclopedias, and basic science books. The room probably had thirty shelves from floor to ceiling and a waist-high card catalog, which was our internet. The librarian, Blanche Caffell, had been my first-grade teacher, known for her lively story times. She made these big thick felt boards to serve as backgrounds for the antics of Mole and Toad in “The Wind in the Willows” or any story she was reading that day.

She immediately set me to work. She said there was a pile of missing books that might be on the shelves but were out of place. Could I find them? It was a typical tedious job, suitable for keeping a kid busy. But I loved it. You needed a detective-like person, I told her. That was exactly what I needed, she replied. I took the cards for the missing books and roamed the shelves until I found each one.

Where do they go? I asked, staring at a stack of books I had found. She explained that non-fiction books were cataloged according to a numerical range from 000 to 900. To remember the Dewey Decimal System, she told me to remember a simple story about a caveman gradually posing more complex questions, starting with “Who am I?” (which is 100: philosophy and psychology) all the way to “How do I leave a record for others?” (900: history, geography, and biography).

About six months later, in June 1964, my sister Libby was born, and we moved into a new house. At that time, we were told Crumpet was happily living on a nearby farm.

At my new school, the librarian said she didn’t need an assistant. Eventually, my parents decided it would be better for me to finish fourth grade at my original school and study in the library with less disruption. So much was changing in the family, and I’m sure they knew it was wise to let me stay in the comfort of books a little longer.

Good morning, good morning, good morning, good morning! This was the song my mom sang every morning after I started fifth grade. The song came through the intercom connecting the downstairs bedroom to the upstairs kitchen, where she was making breakfast. I’m not sure if the size of our new house warranted the need for an intercom, but for my mom, it was a tool for efficiency, allowing her to wake us up in the morning, get us ready for church, and call us to meals—without interrupting whatever else she was doing. The call from the intercom meant to come upstairs immediately.

The eastward journey was in some ways a celebration and a benefit for Kristi and me. My sister was starting at Roosevelt High School in the fall, and I was going to a new school too. My parents decided to send me to an exclusive boys’ private school in North Seattle—Lakeside School. This decision was not easy for them. They both grew up in public schools—my mom was a graduate of Roosevelt—and believed in supporting the public education system. The $1,400 annual tuition was a significant expense for my dad’s salary. But they could see I needed more challenges and lacked motivation. Maybe Lakeside would inspire me, they thought. At first, I hated the idea. I heard that the older students were required to wear jackets and ties and called the teachers “sir.” When I went to take the entrance exam, I even considered failing on purpose. But once I started the test, I couldn’t hold myself back. My self-esteem overcame me, and I passed.

My seventh-grade life felt first impacted by Lakeside School’s name. The campus was not near a lake but was quietly situated in North Seattle, a twenty-minute drive from my neighborhood. That day, as I sat in my mom’s Ford SUV heading there, it felt far from home.

Founded in 1919, Lakeside was established as a college preparatory school for boys from some wealthy families in Seattle. Initially located on Lake Washington—hence the name—but in the 1930s, it moved to cleared land to build a larger collegiate-style campus. During the six years I spent there, the school would abandon its more conservative preparatory school traditions, abolish the uniform requirement, hire female faculty, and merge with a girls’ school—but when I started in the fall of 1967, every teacher except the librarian was male and white. We had assigned seating at lunch. During school, I fell in love with classic works of youth like “The Catcher in the Rye” and “A Separate Peace,” books that described iconic East Coast prep schools. Lakeside was modeled after those places, with neatly trimmed green lawns and brick buildings with colonnades. It even had a bell tower.

The school was divided into middle school grades seven and eight and high school grades nine through twelve. In the lower campus, seventh and eighth graders generally did not interact much with older students. We middle schoolers spent most of our time in one of the oldest buildings on campus—Moore Hall. The older students had more freedom, and they were undoubtedly the rulers of the school. Sports played a significant role in the school, which was bad news for me. The football team had a long-standing winning streak, and the rowing team had beaten a well-known East Coast school in the national championships, bringing fame to the school.

There were about fifty boys in my class, almost all of whom were white. Their fathers held the kinds of jobs you would expect at a private school in the Pacific Northwest. They were lawyers, doctors, bankers, executives at lumber companies, Boeing engineers—part of Seattle’s elite. One dad owned a steakhouse that would develop into a national chain. Another would found a significant health insurance company. We were not a diverse mix, but I still felt different from many of the other kids. Many seemed very sure of themselves, especially those whose older siblings were at Lakeside, who seemed to know how to act. In the first few weeks, I watched as others quickly found their places, signing up for football, the newspaper, drama, choir, or various other activities. Unlike me, many came with social networks. They knew each other through ski clubs, tennis clubs, or family connections.

Today, any business purchasing a computer system can expect its operating software to have undergone thorough testing for reliability, security, and stability. But that was not the case in 1968. Companies like DEC and its competitors IBM and GE made money off hardware—chips, tape storage drives, and processing units made up everything that constituted a real computer, all housed in boxes the size of refrigerators and the devices connected to them. In contrast, software was just an afterthought, so low in value it could be offered for free. Even if a customer rented or purchased a computer, its operating system (the software that controls the main functions of the computer) typically required a lot of additional testing and debugging before it could be used for everyday work.

DEC reached an agreement with C-Cubed to help improve their software. As long as the new partner found and reported bugs, DEC would waive its monthly rental fees. In industry terms, this was called guarantee testing, which usually involved customers ensuring that their new computer systems operated as promised for a certain period. C-Cubed saw this as an opportunity to delay paying for usage as long as possible.

The deal arranged by Ms. Rona allowed us kids to have open access to their system, with the only stipulation being that when the machine crashed or acted strangely, we had to document it. Ironically, breaking it was a good thing. They preferred to have teenagers discover problems rather than paying customers. Moreover, submitting more bugs meant they wouldn’t have to pay rent for a longer time. C-Cubed needed monkeys with hammers.

After Ms. Rona sought our help, her company’s remodeled car dealership became our second home. In December 1968, Kent, Paul, Rick, and I spent hours and hours at C-Cubed writing and debugging programs, drafting error reports. The new year came and went, Saturdays turned into weekday afternoons, and then extended into evenings. While other kids at Lakeside were studying or playing sports, going to church, or sleeping, we were at C-Cubed, using expensive, high-performance computers for free. Fortunately, that year was one of the snowiest winters in Seattle’s history—over five feet of snowfall—which gave us school breaks, and I spent those days at C-Cubed.

We knew they would eventually kick us out. Like kids scrambling for candy that had fallen from a broken piñata, we had to grab as much as we could before it all disappeared. One night that winter, while sitting in my bedroom, I thought to myself: Why am I wasting time here when I could be at the computer?

One night while rummaging through a dumpster, we found a thick stack of documents filled with lines and concise commands like ADD, SUB, PUSH, and POP. We brought it inside and spread it out on the table. We hit the jackpot! This was part of the instruction set for the PDP-10 operating system. Those instructions—source code—were forbidden to us. What we found was mysterious, just lines of code, and we needed to reverse-engineer to figure out what they did. But that crumpled, coffee-stained piece of paper was the most exciting thing we had ever seen.

The printed output was written in machine language, the most basic code a programmer could use. Machine code allowed you to write programs that ran faster than anything created in high-level languages like BASIC, but it was laborious, requiring the user to define every step the computer needed to take to perform a task. For example, in BASIC, instructing the computer to display “Hello” only required one command (PRINT “Hello”), while in machine code, the same task might require twenty-five lines of character-by-character instructions. For a novice, this code was nearly unfathomable, a secret language that only true experts could speak, and that was precisely why I wanted to learn it.

The better my programming skills became, the more I wanted to do something practical—write a program that might actually be useful to someone. A few years earlier, I had the same impulse when I realized that no matter how cool the bridges or rockets I drew, I couldn’t build one in the real world. This was different. With a computer, I felt I could create anything I could imagine. At home, my mom cooked from recipe cards she kept in a small wooden box. I borrowed four or five cards, took them to C-Cubed, and designed a simple BASIC program that generated my mom’s meatloaf recipe when prompted with “meatloaf.” In programmer’s terms, this was a trivial program, but it taught me about DATA statements and the READ command.

In the worldview I was gradually forming, the logical thinking and rational reasoning required by math were skills that could be applied to mastering any subject. Intelligence had layers: no matter how good you were at math, your ability to learn in other subjects (biology, chemistry, history, even languages) would be equally strong. My model, though simple, seemed validated in school, and I felt I could connect students’ math abilities to their broader academic achievements in other subjects.

That summer on Hood Canal, I decided to test my theory—on myself. For the first time in my life, I was going to apply myself to school.

Lakeside made you buy all your books. The school had a small bank branch downstairs in Bliss Hall where your parents would deposit money. Throughout the year, you would fill out checks for books and other school expenses (like our computer time). In the bookstore—a table parked in front of the basement classroom—you would tell Joe Nix your courses, and he would disappear behind the shelves for a few minutes, returning with a stack of books for you to fill out checks for. Joe was the night custodian—a beloved figure who always had his German shepherd with him—who also served as the school’s clerk. When I showed him my schedule during the first week of school, he greeted me with a bright smile. Filled with new determination, I devised a plan that I believed would be a huge success.

He looked over my list of courses—Ancient and Medieval History, English, Latin, Biology, and Honors Algebra—and I told him I wanted two copies of each book. He paused for a moment, clearly confused by the request, then turned and picked up those books. To this day, I’m still not sure if my parents noticed they paid double.

After we were kicked out of the C-Cubed castle, Paul successfully persuaded the computer lab at the University of Washington to let us in, where we honed our programming skills all summer long. He didn’t tell Kent or me about his strategy, because later he confessed that we looked too young to pass for college students, and he feared our presence would jeopardize our privileges. By mid-year, he made up for it by bringing us back to C-Cubed. By then, the company’s relationship had cooled, and they asked Paul to help with some programming work.

That’s how, after a six-month break from computers, I began joining Paul at C-Cubed and continued working on my war simulation. I gradually got parts of it functioning. I would print out the program, mark the errors, input new code, and print it out again. Eventually, those punched computer papers extended over fifty feet. When we got the bad news, some functions were running quite smoothly: C-Cubed was going to close. This startup had only been around for a little over a year and had failed to sign many big clients. Their initial projections for computer usage had not materialized. Worse, Boeing, Seattle’s largest employer, was in serious trouble. The airline’s orders had dropped, and Boeing had borrowed heavily to develop its first jumbo jet (the 747), leading to layoffs in the thousands. These ripple effects dragged Seattle into an economic recession, affecting many businesses. Within a year, someone had posted a famous billboard on Highway 99 that read, “Will the last person leaving Seattle turn out the lights?”

When writing my Harvard application essay, I condensed my entire computer background into six hundred words, expressed in neat cursive on my mom’s Selectric typewriter. Starting with the “productive arrangement” with the local company (C-Cubed), through salaries, course schedules, and our automatic traffic counter, I told the story of the Lakeside programming group. As for my teaching experience, I admitted, “Of all the things I’ve done, this has been the hardest. Usually, some students develop a strong interest in computers in class and continue to work with them… On the other hand, there are some students who find computers more mysterious after I leave than when I first entered the classroom.”

If the admissions officer reading my essay made it to the end, they might have been surprised by my conclusion: “Working with computers has proven to be a great opportunity to have fun, make some money, and learn a lot. However, I do not intend to continue focusing on this field. What I am currently most interested in is business or law.”

In fact, I knew a career in computers—especially software—was a possible path, even the most likely one, if microprocessors produced the cheap, general-purpose computers that Paul and I hoped for. But by the fall of 1972, it was still an unknown. For now, to satisfy my own curiosity and as a backup plan, I wanted to explore new worlds.

I believe you know that Paul and I were once again moving forward on the path (a path that proved to be quite long) equally and somewhat enthusiastically. I really want to thank you for the special friendship you showed when we were both facing difficulties. I truly hope that we both come to realize the absurdity of our positions sooner or later. Your willingness to move everything I left in the apartment back to my house was an extension of the personal consideration you showed throughout the summer. I hope I can do the same, although overall it was a very wonderful summer… Your friend, Trey.

On a dark Sunday morning in December 1969, a U.S. Army truck drove onto the Harvard University campus. Soldiers in camouflage unloaded large crates containing parts of DEC mainframes dismantled during the Vietnam War, a gift from the U.S. Department of Defense. These parts were as big as refrigerators, opened and connected together in Harvard’s Aiken Computation Laboratory, forming a PDP-10, the same model I had been programming for five years before enrolling in the fall of 1973.

The nighttime delivery successfully evaded the anti-war protesters who had been agitating against the university’s involvement in defense-related research. The students shouting slogans were not entirely wrong: at that time, the military was likely the biggest customer of the computer industry, and the Cold War fears of the Soviet Union had led to massive public funding for universities to develop automated systems for missile guidance, submarine control, and detecting intercontinental ballistic missile launches.

When I arrived in Cambridge for freshman orientation a few weeks later, the government’s significant investments in defense technology had already changed the Boston area. DEC and dozens of other companies had emerged from MIT’s projects to develop computers and other military technologies. Before Silicon Valley became the high-tech center of America, Route 128, stretching sixty miles around Boston, had held that title.

A few weeks after I first walked into Harvard’s Aiken Computation Laboratory, I got a glimpse of the legacy of government funding. I went there to meet the lab director. In the lobby, I saw a massive machine labeled Mark I, the prototype computer developed by Howard Aiken, after whom the lab was named. Aiken was a naval commander in the 1940s who collaborated with IBM to develop the Mark I for calculating missile trajectories. It was later used in the Manhattan Project. The Mark I was a breakthrough at the time, a huge calculator made of wheels and electronic relays, a fifty-foot-long machine that could perform addition, subtraction, multiplication, and division faster than a human. When I first laid eyes on the Mark I, it was just a part of an original machine, a non-functioning museum exhibit.

Across the hall, I could see a PDP-10 in the room that the Aiken lab referred to as Harv-10. DARPA, the Defense Advanced Research Projects Agency, was funding the Aiken lab so that Harvard’s engineering faculty and students could use this system to experiment with new programming methods to make software faster, more reliable, and cheaper. The agency also installed a connection that linked the Harv-10 to the ARPA network, which would later become better known as ARPANET. The Aiken lab was one of dozens of computer centers across the country that began testing email and other new communication protocols that would form the foundation of the internet.

The next day at MITS, they were ready with a machine that had 6K of memory and a paper tape reader. Paul entered his bootstrap code, which took some time: each byte had to be entered by setting eight data switches. Then he started the paper tape reader. Our BASIC program took about seven minutes to input into the computer. Finally, it reached the end of the tape and began running the program, and… nothing happened. It didn’t work.

With this step, the first software for the first personal computer was born.

Paul, sipping juice, said at the celebratory dinner at Aku Aku, “I don’t know who was more surprised, me or them!” He recalled that when our software combined with their computer to calculate 2 + 2, the president of MITS was astonished. “Oh my God, it printed four!”

Paul was amazed that our little program was flawless at its debut. At the same time, Ed and MITS’s chief engineer, Bill Yates, were also shocked that their machine was actually doing something.

Inspired by the Altair and its Intel 8080 processor, HP engineer Steve Wozniak bought a MOS Technology 6502, the cheapest microprocessor he could find, and quickly built his own computer prototype. Like many members of the Homebrew Club, Wozniak was motivated by the passion for engineering and building something to share with the club. Until his friend Steve Jobs saw the prototype. Jobs had just returned from a seven-month trip to India, which he later said was a quest for self-discovery. Within a year, he shed his saffron robe, grew his hair long, and convinced Wozniak that their computer hobby could turn into a business. Soon, they named the company Apple and began selling their first computer—the Apple I.

While MITS computers continued to sell well, only a small fraction of customers paid for BASIC. In the fall, Ed Roberts wrote a column in MITS’s newsletter, “Computer Notes,” gently chastising customers for not paying for the software. I thought his tone was not strong enough. One night that winter, I wrote down my feelings on a piece of paper in my dorm room and sent it to a writer at MITS named Dave Bunnell, who edited “Computer Notes.” Dave sent my letter to some computer magazines and the Homebrew Computer Club newsletter, and then published it in the February 1976 issue of “Computer Notes.”

Is it fair? It’s unfair to retaliate against MITS for the problems they might encounter with pirated software. MITS does not make money from selling software. The royalties, manuals, tapes, and all operating costs barely break even. Pirated software hinders the development of quality software. Who can work professionally for free? What hobbyist can spend three person-years programming, finding all the bugs, documenting the product, and distributing it for free? In fact, no one besides us had invested significant money in amateur software. We had written 6800 BASIC and were working on 8080 APL and 6800 APL, but had little motivation to provide this software to hobbyists. To put it bluntly, the result of piracy is theft.

What about those who licensed the right to resell Altair BASIC? Are they making money off toy software? Yes, but those who reported us might ultimately suffer. They tarnished the reputation of hobbyists and should be kicked out of any club gatherings they attended.

The two main goals we wrote down were (1) to expand our scale and reputation and (2) to make money. That letter marked the next phase of a collaborative effort to establish ourselves as an independent company. We all agreed that Microsoft would be our primary focus for at least the next two years.

Microcomputers quickly became popular.

This was the headline of a summer 1976 issue of “Business Week,” about a year after we signed our contract with MITS. I loved the story because it was not the typical publication reported by industry news or computer enthusiast newsletters, but rather aimed at readers in our corner of the computer industry. I thought the readers of “Business Week” were investors and executives—most of whom did not yet own computers but might be inclined to buy one if they were easier to use.

Using a blue ballpoint pen, I marked what I thought were the key paragraphs: “Today, the home computer industry is beginning to resemble the mini-mainframe computer industry—complete with a dominant competitor. The IBM of the home computer world is MITS, which was founded seven years ago by engineer H. Edward Roberts in his garage in Albuquerque, New Mexico.” The article noted that MITS had sold eight thousand Altair computers the previous year, bringing in $3.5 million in revenue. The article pointed out that although there were competitors, Altair’s early lead made it the industry standard.

As I read, I thought: even if MITS is the IBM of the moment, it won’t last. One reason is that if IBM decided to make personal computers, it would likely replace MITS as the IBM of the moment. I knew Ed Roberts was also worried that major electronics companies would join the competition. To Ed, the most frightening company was Texas Instruments. In the early 1970s, MITS was the first to launch programmable kit calculators used by engineers and scientists. Once that market reached a certain size, large companies like Texas Instruments would introduce ready-made low-cost alternatives that would almost eliminate MITS. Ed was very concerned that the same thing would happen again with personal computers.

TI was using its own processors, which meant we would have to write a new version of BASIC from scratch. This would require at least two people working for months. Monte was once again willing to spend the summer in Albuquerque, but since Rick had left, we needed to hire another programmer. After we signed the agreement with TI, I called Bob Greenberg, who had taken a few math classes with me at Harvard, and I knew he was considering a position at the time. He told me, “I’m the person you’re looking for.”

Whether we had enough cash to pay him was another question. MITS had offered a small royalty but refused to pay the full amount it owed us, over $100,000.

The arbitration hearing lasted about ten days. I attended all the testimony as a representative of Microsoft. Eddie Curry played the same role for MITS. Rick, Paul, and I were also subpoenaed, along with Ed Roberts, Eddie, and various personnel from the company. Aside from Microsoft’s interests, I found the whole process fascinating. Fully displaying Kent’s style, I showed up every day with a huge briefcase filled with all the documents I might need. I would rummage through the briefcase, pulling out documents one by one—not just to find references but to show off. I wanted to achieve the opposite effect of not bringing books in high school: Look, all these documents! They must be very well prepared!

Known as the “Big Three of 1977,” these three machines brought the personal computer revolution into the mainstream while others fell behind. (Texas Instruments, the giant we had once been excited to partner with, never succeeded in the personal computer space.) On each of the Big Three machines, we installed a customized version of our BASIC as requested by the manufacturers. On the RadioShack machine was Level II BASIC, on the Apple machine was Applesoft—a portmanteau of Apple and our name—and on the PET machine was simply Commodore BASIC. In a version tailored for Commodore, we added a little surprise in the code: if PET users happened to input the command WAIT 6502,1, a word would appear in the upper left corner of their screen: Microsoft.

Microsoft was no longer dependent on MITS, and when Paul and I found it difficult to hire programmers in Albuquerque in the spring of 1978, we wrote a memo outlining alternative locations for our ten or so employees. I listed Seattle, Dallas-Fort Worth (near our big clients Tandy and TI), and Silicon Valley as possible sites. Paul had a strong attachment to our hometown. He was fed up with Albuquerque’s hot weather and longed for the lakes and Puget Sound of Seattle, wanting to be closer to his family. Most of our employees were open to any location (though a few wanted to stay in Albuquerque). After careful consideration, I concluded that Seattle was the best choice for our needs: the University of Washington was an excellent source of programmers, and the distance from Silicon Valley provided a higher degree of confidentiality, reducing the risk of employees leaving for competitors. Of course, it was also my mom’s first choice. Once we decided on Seattle, she couldn’t help but cut out real estate ads from the newspaper, often adding her own comments (like “This location is very close to the bridge—I think it’s a great possibility”).

In December 1978, during our last full month in Albuquerque, Bob Greenberg won a prize for a free family portrait in a contest. He sent out a memo titled “Team Spirit,” asking everyone to go to a photo studio behind the Shanghai restaurant. The family he brought was eleven of our twelve employees (one person was home that day). The posed photo we took would become an iconic image of Microsoft in the 1970s, featuring wide collars, curly hair, and five thick beards.

Of course, there were always things to say. My mom often reminded me that I was merely the steward of any wealth I acquired. She said that wealth brought responsibility and must be given generously. I regret that my mom did not live to see how I have tried to fulfill that expectation: she passed away from breast cancer at sixty-four in 1994. In the years after my mom’s death, my dad helped us establish the foundation and served as co-chair, bringing the same compassion and integrity he had shown in his legal career.

For most of my life, I have focused on the future. Even now, much of the time, I am striving for breakthroughs that may take years to achieve, if at all. However, as I age, I find myself looking back more and more. It turns out that piecing together memories helps me understand myself better. The miracle of adulthood is realizing that when you strip away all the years and all the learning, much of your essence was there from the beginning. In many ways, I am still that eight-year-old child sitting at Gami’s table. I feel the same sense of anticipation, a child alert and eager to understand everything.

My mother, Mary Maxwell Gates (sitting on the couch next to her grandparents, in the upper left corner), grew up in a family of bankers who loved games, sports, and community service. A natural leader, she rode the biggest tricycle in the childhood photos (in the upper right corner).

My sister Libby was born in 1964, becoming the most social and athletic member of our family. As the youngest, nine years younger than me, Libby remembers growing up in a busy household filled with bustling siblings and parents.

When I was three, I appeared in the local newspaper with my mom, who was hosting a Junior League project that showcased museum exhibits to elementary school students, featuring a set of old medical tools.

My mother had high expectations for the family, and my parents believed in the importance of giving back to the community long before that phrase became popular.

The space race and hopes for science were part of growing up in the 1960s. It’s no wonder I checked “astronaut” on my fifth-grade “What I Want to Be When I Grow Up” form. But “scientist” was my dream job: being someone who studied the mysteries of the world all day was perfect for me.

My grandmother, whom we called Gami, was an indispensable presence in our early lives. After my grandfather passed away, she turned her love and attention toward me and my sisters, sometimes joining us on family vacations, like this trip to Disneyland.

In the early 1960s, my parents and a group of friends began renting Cheerio Lodge Cottages on Hood Canal for two weeks every July. For a kid, it was paradise. My dad was the mayor of Cheerio, a fun director, and a manager for the kids, while also hosting the opening ceremony for the Cheerio Olympics. The events focused more on agility and determination than just physical prowess, but whatever the event, I always gave it my all, striving to stand on the podium at the end of the day. I was low on agility but high on determination.

Our family lived according to the routines, traditions, and rules established by my mother. As my father said, “She runs an orderly household.” Christmas. Planning began in early autumn, and my mom would review notes from the previous year’s holiday to see where improvements could be made. From handmade cards to our annual ice-skating party to the matching pajamas we wore on Christmas morning, we went all out. Even occasionally when my sisters and I would roll our eyes at these traditions—if any one of them were skipped, it would feel like a loss. Christmas remains one of our favorite memories.

When I was eight, I joined the Boy Scouts. Four years later, when I transferred to Troop 186, hiking, camping, and climbing were booming in America, and Seattle was becoming recognized as a mecca for outdoor activities. Our troop made getting scouts into the mountains for hiking and camping a primary reason for its existence.

That summer in ninth grade, a senior scout invited me to join a hiking trip across the Olympic Coast Trail (now known as the Pacific Crest Trail). This trail runs along the coastline of Vancouver Island and is known for its rugged terrain of storms, rocks, and tricky currents. The trip required taking a seaplane, fording rivers, and climbing cliffs, and it was the most challenging adventure I had experienced to date, but also the most meaningful. I fell in love with it.

Kent Evans (left in the photo) and I quickly became best friends in eighth grade at Lakeside Private School, where I attended middle and high school.

In the fall of 1968, Lakeside acquired a teletype machine. Kent and I became regular users, as did Paul Allen (in the middle of the photo) and Rick Weiland (on the right). Paul and Rick were two years older than us, but we quickly became friends as we all worked to learn how to write our first programs. We called ourselves the Lakeside Programming Group.

According to my class photo, I looked younger than my actual age throughout high school (and even afterward). Working with the Lakeside Programming Group, hiking, scouting, and school, I slowly began to understand who I was and who I wanted to become.

As a tenth-grade student, I served as a legislative assistant in our state capital, Olympia (as shown in the photo), and later spent part of a summer before graduating high school as a congressional aide in Washington, D.C. It was nearly impossible to be exposed to Congress without being deeply captivated; that experience sparked my lifelong interest in politics and government.

In my emerging worldview, I established a hierarchy of intellect: no matter how good you were at math, your abilities in other subjects like biology, chemistry, history, or even languages would be equally strong. After leaving Lakeside, I was convinced my path in life would be mathematics. Harvard was the next step toward that future.

In April 1975, Paul and I came up with the name for our company: Microsoft (which we would eventually drop the hyphen). Our only product was 8080 BASIC, written during my sophomore year. Our Lakeside friend Rick (on the left in the above photo) quickly joined us in Albuquerque, where we initially worked in an old shopping mall office space. As Microsoft grew, the time I spent on the company increased; I took my second leave of absence from Harvard in the winter of 1977 and never returned. We began attracting media attention— in the photo on this page, I’m doing one of my first television interviews—but it wasn’t until we hired our first employees outside our circle of friends that Microsoft felt like a real company.

Gami was always a steady voice in my ear during my early growth at Harvard and Microsoft.

My parents were my strong support and source of opinions; they recognized early on that Microsoft was becoming an important company. My mother’s understanding came more gradually. For a long time, she believed things would eventually settle down, and I would earn my Harvard degree.

My mother expected me to meet her very high standards, but she also supported and encouraged me as much as she could, sometimes by example, like when she was appointed to serve on the United Way board in 1980. She often said that wealth meant a responsibility to give. I regret that she did not live long enough to see how I have tried to fully meet that expectation.

I have written several books, but writing a memoir is a different experience for me. Looking back at my early life and sifting through memories feels like it has a life of its own. What surprises me is that the deeper I go, the more I enjoy analyzing my past and what it has brought me intellectually and emotionally. I commit to continuing this journey and plan to write another memoir about my time at Microsoft and a third about my current life and work with the Gates Foundation.

While writing this memoir, I was fortunate to have Rob Guth extract, guide, and shape my memories. For over a decade, he has dug deep, talking to my friends and family, and he has become a living archive of my memories and experiences. He has a knack for discovering themes and helping me craft a compelling narrative, making this book more than just a collection of anecdotes; I couldn’t have completed this book without him.

I am deeply grateful to Courtney Hodell, whose sense of story and wise advice have guided me since the conception of this book years ago. Susan Freinkel’s experience as a writer and editor has been invaluable in shaping and clarifying my story. Thanks to the researchers, writers, and experts, including Chris Quirk, David Pearlstein, Harry McCracken, Lucy Woods, Pablo Perez-Fernandez, Tedd Pitts, Tom Madams, Wayt Gibbs, and Yumiko Kono, who supported “Source Code” in various ways, laying a solid foundation for this book.

I am very grateful to the many friends who were willing to be interviewed and share their stories and memories from my early life.

Finally, I want to thank my children, Jennifer, Rory, and Phoebe. Being your father and watching you grow has been the greatest joy of my life. While writing this book, I thought about how proud your grandparents and great-grandparents would be of you for becoming such remarkable people.
