Career Bass took control of the family business in 1968. His investments include oil and gas. Along with his father and two of his brothers, he was the largest shareholder in The Walt Disney Company from 1984 until after the stock market crash in 2001. Bass was forced to sell his Disney holdings as a result of a margin call. He turned the $50-million family company he inherited into a $14-billion investment group.
