Along with Bill and Melinda Gates, Warren Buffett is a foundation trustee, helping to shape our vision and develop strategies to address some of the world's most challenging inequities.

Buffett is a U.S. businessman and philanthropist. As chairman and chief executive officer of Berkshire Hathaway Inc ., he has invested in a broad range of companies, from See's Candies to Geico Insurance to Fruit of the Loom.

In 2006, Buffett pledged most of his fortune to the Gates Foundation and to four charitable trusts created by his family—the Susan Thompson Buffett Foundation, the Howard G. Buffett Foundation, the Susan A. Buffett Foundation, and the NoVo Foundation (led by Peter A. Buffett). His gift to the Gates Foundation of 10 million shares of Berkshire Hathaway stock, to be paid in annual installments, was worth approximately $31 billion in June 2006.

Warren attended the Wharton School at the University of Pennsylvania and received his bachelor's degree from the University of Nebraska. In 1951, he earned a master's degree in economics from Columbia University.

Warren and his late wife, Susan Thompson Buffett, raised three children: Susie, Howard, and Peter. Now married to Astrid Menks Buffett, Warren lives and works in his hometown of Omaha, Nebraska.
