Biography

William Henry Gates III was born on October 28, 1955, in Seattle, Washington. His father, William H. Gates Sr., was a well-known attorney, and his mother, Mary Maxwell Gates, was a schoolteacher and active community leader. Gates grew up in a home that valued intellect, ambition, and competition. He attended the private Lakeside School in Seattle, where, at age 13, he discovered his passion for programming by spending countless hours learning to code on early computer systems. At Lakeside, he met Paul Allen, and their friendship would later transform the technology industry.

In 1973, Gates started at Harvard University, studying mathematics and taking high-level computer science courses like Math 55. However, his interest shifted toward the developing personal computer market. In 1975, after seeing an ad for the Altair 8800 microcomputer in Popular Electronics, Gates and Allen reached out to its maker, MITS, claiming they had created a BASIC interpreter for it. They quickly developed the software, and the successful demonstration led to the founding of Microsoft later that year. Gates left Harvard to manage the company full-time, moving Microsoft from Albuquerque, New Mexico, to Washington in 1979.

Microsoft's success took off in 1980 when IBM chose it to provide an operating system for its new PC. Gates acquired an existing system, turned it into MS-DOS, and arranged to license it to other manufacturers. This move established Microsoft as a major player in PC software. Microsoft went public in 1986, and the resulting stock surge made Gates the world's youngest billionaire in 1987 at 31. He was Microsoft's CEO for 25 years, driving the creation of Windows, Office, and expansions into internet and enterprise software. Gates stepped down as CEO in 2000, passing the baton to Steve Ballmer, and gradually took on advisory roles until he left the board in 2020.

Outside of business, Gates became a leading philanthropist. In 2000, he and Melinda French Gates established the Bill & Melinda Gates Foundation, which became the largest private charity worldwide. The foundation has allocated tens of billions of dollars to global health, vaccine distribution, agricultural development in low-income countries, and U.S. education reform. Gates has been especially active in efforts to eliminate polio and malaria and in funding vaccine research, even during the COVID-19 pandemic. Gates and Melinda French Gates divorced in 2021, though their foundation work continued jointly until 2024. His commitment to philanthropy was formalized with the Giving Pledge, a project he started with Warren Buffett, urging billionaires to donate most of their wealth to charitable causes.

Before Fame

Gates grew up in Seattle when computing was shifting from a tool for large institutions to something with broader potential. His parents noticed his intellectual abilities early on and enrolled him in Lakeside School. There, he had access to a General Electric computer terminal in 1968, giving him his first experience with programming at a time when most people hadn't even seen a computer. He and fellow student Paul Allen formed a small group of enthusiasts who found ways to exploit bugs in the school's computer system to get free access, showing both technical skill and a willingness to push boundaries.

By his early teens, Gates had written his first commercial software, a class scheduling program for Lakeside, and co-founded a traffic-counting company called Traf-O-Data with Allen. These early projects showed not only his programming ability but also a knack for finding commercial uses, setting the stage for his future career. By the time he got to Harvard in 1973, the personal computer revolution was just starting, but Gates was already in a position, thanks to years of hands-on experience, to see and seize its potential more quickly than most.

Did You Know?

  • 01.Gates read the entire World Book Encyclopedia series from beginning to end as a child, prompting his parents to place limits on his reading at the dinner table.
  • 02.The BASIC interpreter Gates and Allen wrote for the Altair 8800 in 1975 was completed without access to the actual hardware; they tested it on a software emulator and it worked correctly the first time it ran on a real Altair.
  • 03.Gates took a course called Math 55 at Harvard, widely considered one of the most difficult undergraduate mathematics courses in the United States, covering in one year material typically spread across several graduate-level classes.
  • 04.He was awarded an honorary degree by Harvard in 2007, more than three decades after dropping out, and delivered the commencement address at the same ceremony.
  • 05.Gates's personal library includes an original copy of the Codex Leicester, a collection of scientific writings by Leonardo da Vinci, which he purchased at auction in 1994 for approximately $30.8 million.
