Bill Gates helped put a computer on almost every desk in the world. He and his school friend Paul Allen started Microsoft in 1975, and its software, especially the Windows operating system, became the standard for personal computers. His fierce competitiveness made Microsoft one of the most valuable companies on Earth, and it also led to a major antitrust case in the United States. In later life he shifted his focus to philanthropy, funding work on vaccines, disease eradication and global health through his foundation. His career spans two very different kinds of influence, technology and charity.
