Warren Edward Buffett (/ˈbʌfɪt/; born August 30, 1930) is an American business magnate, investor, philanthropist and the Chief executive officer, President, and Chairman of Berkshire Hathaway. He is considered by some to be one of the most successful investors in the world, and as of August 2017 is the second wealthiest person in the United States, and the fourth wealthiest in the world, with a total net worth of $76.9 billion.
Born in Omaha, Buffett developed an interest in business and investing in his youth, eventually entering the Wharton School of the University of Pennsylvania in 1947 before transferring and graduating from University of Nebraska–Lincoln at the age of 19. Buffett went on to enroll and graduate from Columbia University where he learned and eventually molded his investment philosophy around a concept pioneered by Benjamin Graham–value investing. He attended New York Institute of Finance to specialize his economics background and soon after began various business partnerships, including one with Graham. After meeting Charlie Munger, Buffett created the Buffett Partnership. His firm would eventually acquire a textile manufacturing firm called Berkshire Hathaway and assume its name to create a diversified holding company.
