Lore & Background
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, inspired by a book he borrowed from the Omaha public library at age seven, One Thousand Ways to Make $1000. 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 approach 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.
Buffett 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.
Reader's Guide
Warren Buffett's significance lies in his embodiment of value investing principles, which he learned from Benjamin Graham and applied to build Berkshire Hathaway into a leading conglomerate. His approach—looking at stocks as businesses, using market fluctuations to advantage, and seeking a margin of safety—became cornerstones of investing. Buffett's frugality and commitment to philanthropy are notable: he met Chuck Feeney and pledged to give away 99 percent of his fortune, primarily to the Gates Foundation until 2026. In 2010, he founded The Giving Pledge with Bill Gates and Melinda French Gates, encouraging billionaires to pledge at least half their wealth. His legacy includes being called the 'Oracle' or 'Sage' of Omaha, reflecting his massive fortune derived from business and investment success. Buffett's career spanned from his father's brokerage to partnerships and ultimately Berkshire Hathaway, where he served as chairman from 1970 to 2026.
