Warren Buffett: Biography, Achievements & Lasting Legacy

Warren Edward Buffett ( BUFF-it; born August 30, 1930) is an American investor and philanthropist who is the chairman and former CEO of the conglomerate Berkshire Hathaway. As a result of his success, Buffett is one of the best-known investors in the world. According to Forbes, as of January 2026, Buffett's estimated net worth stood at US$148.9 billion, making him the ninth-richest person in the world.

Buffett was born in Omaha, Nebraska. The son of U.S. congressman and businessman Howard Buffett, he developed an interest in business and investing during his youth. He entered the Wharton School of the University of Pennsylvania in 1947 before graduating from the University of Nebraska in Lincoln at 20. He went on to graduate from Columbia Business School, where he molded his investment philosophy around the concept of value investing pioneered by Benjamin Graham. He attended New York Institute of Finance to focus on his economics background and soon pursued a business career.

He then began several business ventures and investment partnerships, including one with Graham. He created Buffett Partnership Ltd. in 1956 and his investment firm eventually acquired textile manufacturer Berkshire Hathaway, applying its name to a diversified holding company. Buffett emerged as the company's chairman and majority shareholder in 1970. In 1978, fellow investor and long-time business associate Charlie Munger joined Buffett as vice-chairman.

From 1970 to 2026, Buffett presided as the chairman and largest shareholder of Berkshire Hathaway, one of America's foremost holding companies and world's leading corporate conglomerates. He has been referred to as the "Oracle" or "Sage" of Omaha by global media as a result of having accumulated a massive fortune derived from his business and investment success. Buffett adheres to the principles of value investing and frugality despite his wealth. Buffett has pledged to give away 99 percent of his fortune to philanthropic causes, primarily via the Gates Foundation. He founded The Giving Pledge in 2010, with Bill Gates and Melinda French Gates, whereby billionaires pledge to give away at least half of their fortunes. At Berkshire Hathaway's investor conference on May 3, 2025, Buffett requested that the board appoint Greg Abel to succeed him as the company's chief executive officer by the year's end while he remained chairman.
