Chairman of the board, Berkshire Hathaway
Warren Buffett turned an ailing textile company into one of the world's largest conglomerates over six decades. Since the start of 2026 he is no longer CEO — that role passed to Greg Abel — but he remained chairman of the board and by his own account still comes into the office five days a week. His shareholder letter remains the most widely read document in investing.
