In 1970, Sid Bass, a classmate of Rainwater, invited him, then 26 years old, to manage the Bass family investments. From 1970 to July 1986, Rainwater served as the chief investment advisor to the Bass family. He was given $5 million to invest during his first year and managed to lose it all. Rainwater then sought a more methodical investment strategy by studying investors including Warren Buffett, Benjamin Graham, and David Dodd.^[10] Rainwater eventually transformed the Bass family fortune from $50 million into $5 billion, amassing $100 million for himself by the time he started investing his own capital in 1986.^[11][7]
