If you are not familiar with Robert Wilson take some time after reading his Obit in BB posted below to read the Street.com article from 2000. He was a low-profile guy I never had the chance to meet but the interview in 2000 clearly shows even at 73 he was amazingly sharp.
He was one of the original Hedge fund managers from the late 60's like Biggs, Steinhart, Buffett, etc.
TSC interview: Robert Wilson was one of the great stock investors of the past 50 years. He started with $15,000 and had a miserable rate of return in the early years. But from 1960 on, he turned $70,000 into $225 million over 26 years before retiring in 1986 at age 59. In his day, Wilson was a peer of Warren Buffett and George Soros.* Wilson's investment strategy was to go both long and short -- long because he believed in the long-term future of America and short because he never wanted to be wiped out in a downturn
