Bill Gates, born William Henry Gates III in Seattle in 1955, is an American businessman and philanthropist. He was privately educated at Lakeside School, where he met his childhood friend Paul Allen, and he left Harvard in his junior year in 1975 to co-found Microsoft with Allen.

He served as Microsoft's chief executive until 2000 and later moved to work full-time on the Gates Foundation, which he founded and chairs. He is known for his role in the personal computer revolution and, with Melinda French Gates and Warren Buffett, for founding the Giving Pledge in 2010. In 2025 he announced he would give away 99% of his fortune over 20 years, mostly through the foundation.
