Who is Warren Buffett?
Warren Edward Buffett bought his first stock as a child, studied under Benjamin Graham at Columbia, ran partnerships in the 1950s–60s, and took control of Berkshire Hathaway — originally a struggling textile mill — transforming it into a holding company. With Charlie Munger (d. 2023) he popularized buying wonderful businesses at fair prices, using insurance float as cheap capital, and writing annual letters that became required reading on Wall Street.
Berkshire’s empire spans GEICO and other insurers, BNSF Railway, Berkshire Hathaway Energy, manufacturing and retail holdings, and a huge public-equity book (historically including Apple as a signature position). Buffett pledged most of his fortune to philanthropy (notably the Gates Foundation and family foundations) via the Giving Pledge ethos he helped champion. In 2025–2026 Berkshire’s succession became real: Greg Abel succeeded him as CEO (Buffett remained the spiritual and capital-allocation icon; titles settled as chairman emeritus / senior role depending on Berkshire’s formal disclosures — see Reuters Berkshire glance coverage).
