Berkshire Hathaway, the conglomerate Warren Buffett chairs and has led as CEO, stands as the central fact of his public life — a sprawling enterprise that has defined his decades-long career as an investor, financier, and entrepreneur.

Buffett was born on August 30, 1930, in Omaha, and his education traced a path through several institutions: Jackson-Reed High School, the University of Nebraska–Lincoln, the Wharton School and the University of Pennsylvania, Columbia Business School, and the New York Institute of Finance. That sequence of schooling — moving from the Midwest to the East Coast and through some of the country's more demanding business programs — preceded his emergence as one of the most closely watched figures in American finance. He works in English and holds United States citizenship, spending much of his professional life rooted in Omaha, the city where he was born.

His roles have accumulated over time: investor, economist, shareholder, entrepreneur, and philanthropist. The philanthropic dimension is notable alongside the financial one, as Buffett has pursued both simultaneously rather than treating charity as a retirement project. He received the Presidential Medal of Freedom, a recognition awarded by the United States government. As of January 2026, Forbes estimated his net worth at approximately $148.9 billion, placing him ninth among the wealthiest people in the world — a figure that reflects his continued position at the head of Berkshire Hathaway, where he serves as chairman and CEO.
