Warren Buffett

An American investor and businessman. In 1962, Buffett began buying shares in Berkshire Hathaway, eventually taking a controlling stake in the company. He expanded Berkshire Hathaway's business into insurance and used the proceeds to finance other investments. These investments turned Buffett into a billionaire in 1990. In 2008, he was the richest man in the world, but dropped to second place in 2009.

Nicknamed the "Oracle of Omaha," Buffett is a major proponent of value investing, which holds that it is better to invest in companies based on their intrinsic values rather than their technical information. This philosophy generally has been highly profitable for Buffett. Between 2000 and 2010, under Buffett's guidance, Berkshire Hathaway returned 76% to shareholders.
