In 1973, Bill Gates entered Harvard University to study computer science after discovering his knack for electrical engineering and code while creating software for his high school at the age of 13. Gates would never walk out of Harvard with a degree—or any college with a degree for that matter. Still, some argue the business savvy, technical skills and long-term visions he possessed would be worth much more than a diploma. Because when Gates dropped out in 1975, it was with good reason: He wanted to start Microsoft. His career has been recognized for small flare-ups and constant comparisons with Apple founder Steve Jobs, ongoing philanthropy and technological innovation. Gates has been knighted by the Queen of England, became a billionaire when he was merely 31 years old and developed the Microsoft Disk Operating System for IBM in 1980.
While he is no longer at the helm of Microsoft, Bill Gates continues to leave his mark on history. In 2008, he left Microsoft to dedicate himself full-time to the Bill & Melinda Gates Foundation, which he spearheads with his wife, Melinda Gates. Though their organization, the couple has donated more than $28 billion to various causes. Learn more about this inspiring man and how the world has changed because of him.
