Warren Buffett is chairman and CEO of the holding company Berkshire Hathaway Inc. based in Omaha, Nebraska. He oversees a number of the conglomerate’s subsidiaries. Renowned as the most successful investor of the twentieth century, Buffett is among the wealthiest individuals in the world.
Buffett, born in 1930, is the son of U.S. Congressman Howard Buffett. He was fascinated with making money from a very early age, buying his first stock at the age of 11.
