Sid Richardson Bass (born April 9, 1942) is an American billionaire investor and philanthropist.
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.
Others speculated that the Disney deal slowly fell out of Bass' control after his main adviser Richard Rainwater had left in 1986.
[4] Bass donated $20 million to Yale University for the study of humanities in 1990.
