A passionate techie and a shrewd businessman, Bill Gates changed the world while leading Microsoft to dizzying success. Now he's doing it again with his own style of philanthropy and passion for innovation.

Why you should listen

Bill Gates is the founder and former CEO of Microsoft. A geek icon, tech visionary and business trailblazer, Gates' leadership -- fueled by his long-held dream that millions might realize their potential through great software -- made Microsoft a personal computing powerhouse and a trendsetter in the Internet dawn. Whether you're a suit, chef, quant, artist, media maven, nurse or gamer, you've probably used a Microsoft product today.

In summer of 2008, Gates left his day-to-day role with Microsoft to focus on philanthropy. Holding that all lives have equal value (no matter where they're being lived), the Bill and Melinda Gates Foundation has now donated staggering sums to HIV/AIDS programs, libraries, agriculture research and disaster relief -- and offered vital guidance and creative funding to programs in global health and education. Gates believes his tech-centric strategy for giving will prove the killer app of planet Earth's next big upgrade.

Read a collection of Bill and Melinda Gates' annual letters, where they take stock of the Gates Foundation and the world. And follow his ongoing thinking on his personal website, The Gates Notes.

What others say

“When Gates looks at the world, a world in which millions of preventable deaths occur each year, he sees an irrational, inefficient, broken system, an application that needs to be debugged. It shocks him -- his word -- that people don't see this, the same way it shocked him that nobody but he and [Paul] Allen saw the microchip for what it was.” — Time

Quotes from Bill Gates

A top-quartile teacher will increase the performance of their class — based on test scores — by over 10 percent in a single year. … That means that if the entire U.S., for two years, had top-quartile teachers, the entire difference between us and Asia would go away.

Until recently, over 98 percent of teachers just got one word of feedback: Satisfactory. If all my bridge coach ever told me was that I was ‘satisfactory,’ I would have no hope of ever getting better.
