Early Life and Education
Gates was born on October 28, 1955, in Seattle, Washington, and grew up in the city’s Laurelhurst neighborhood. His father, William H. Gates Sr., was an attorney, and his mother, Mary Gates, served on corporate boards and in community organizations. He attended public school before enrolling at the private Lakeside School in Seattle, where he discovered programming on early computers. He entered Harvard College in 1973 but left in 1975 to pursue Microsoft full time. He has since received honorary degrees from several institutions and remains engaged in education philanthropy, particularly through scholarships and policy advocacy.
Microsoft Cofounding and Leadership
In 1975, Gates and childhood friend Paul Allen founded Microsoft to develop software products for the emerging personal computer market. The company’s breakthrough came with MS-DOS in the early 1980s, followed by Microsoft Windows, which became the dominant operating system for PCs. Gates served as chairman and CEO, overseeing product strategy and business development. He transitioned out of day-to-day management in 2000, became technical fellow and chairman, and later left his formal executive role in 2008 to focus on philanthropy. Microsoft’s long-term influence on software, enterprise technology, and consumer devices remains closely tied to decisions made during his leadership.
