Bill Gates co-founded Microsoft in 1975 with Paul Allen and built it into the most dominant software company of the 20th century by licensing MS-DOS to IBM and then making Windows the operating system of the personal computing era. Born in Seattle in 1955, Gates was a programming prodigy who dropped out of Harvard to pursue his conviction that personal computers would be on every desk in every home. Microsoft's Office suite, Windows, and later Azure and Azure AI became foundational infrastructure for global business. Gates left day-to-day Microsoft leadership in 2000 and has since directed most of his energy and fortune toward the Bill and Melinda Gates Foundation's global health and poverty initiatives.
