Bill Gates is a name synonymous with the personal computer revolution and, more recently, with large-scale philanthropy. As the co-founder of Microsoft, he helped shape the digital age, and as the co-chair of the Gates Foundation, he has directed tens of billions of dollars toward global health and development. This profile examines the key facts of his life, from his early days in Seattle to his current role as one of the world’s most influential philanthropists.
Early Life and Education
William Henry Gates III was born on October 28, 1955, in Seattle, Washington. His father, William H. Gates Sr., was a prominent lawyer, and his mother, Mary Maxwell Gates, served on the board of directors for several organizations, including the United Way. Gates attended Lakeside School, a private preparatory school, where he was first introduced to computers and programming. There, he met Paul Allen, who shared his fascination with technology and would later become his business partner.
Gates enrolled at Harvard University in 1973 but dropped out in 1975 to pursue his entrepreneurial ambitions, a decision that would prove pivotal. At Harvard, he had developed a version of the programming language BASIC for the first microcomputer, the MITS Altair.
Founding Microsoft and the Rise of a Tech Giant
In 1975, Gates and Paul Allen founded Microsoft (a portmanteau of “microcomputer” and “software”) in Albuquerque, New Mexico. Their big break came in 1980 when IBM approached them to provide an operating system for its upcoming personal computer. Gates and Allen acquired a system from another company and adapted it into MS-DOS, which became the standard for IBM PCs and clones. The licensing model they used allowed Microsoft to retain the rights to the software, generating enormous revenue.
In 1985, Microsoft released Windows, a graphical extension to MS-DOS, which eventually became the dominant operating system for personal computers. Under Gates’ leadership, Microsoft grew into one of the most valuable companies in the world. He served as CEO until 2000, when Steve Ballmer took over, and remained chairman until 2014.
Philanthropy and the Gates Foundation
In 2000, Bill and Melinda Gates founded the Bill & Melinda Gates Foundation, initially focused on global health and education. The foundation has since become one of the largest private charitable organizations in the world, with an endowment of tens of billions of dollars. It has funded initiatives to combat diseases such as malaria, tuberculosis, and polio, and has invested heavily in vaccine development and distribution.
In a 2025 interview with the BBC, Gates revealed that the foundation had given away over $100 billion since its inception. He stated that he plans to give away 99% of his fortune over the next 20 years, primarily through the foundation, which is set to close by 2045. Despite his immense wealth, Gates has said that he does not plan to leave the majority of it to his children.

Gates has consistently stated his intention to give away the vast majority of his wealth, emphasizing that his children will be well provided for but will not inherit the bulk of his fortune.
Current Roles and Interests
Today, Gates divides his time between his philanthropic work and his role as co-chair of the Gates Foundation. He is also the founder of Breakthrough Energy, a venture capital firm focused on clean energy technologies. Gates has authored several books, including The Road Ahead (1995) and How to Avoid a Climate Disaster (2021). His memoir, Source Code: My Beginnings, was published in 2024. He remains a prominent voice on issues of global health, climate change, and technology.
