Background
He was born in Corsicana, Texas.
He was born in Corsicana, Texas.
He graduated with a Doctor of Philosophy in Physics in 1953.
He is best known for formulating the Kelly criterion, a formula to determine what proportion of wealth to risk in a sequence of positive expected value bets so as to maximize the rate of growth of wealth. He spent four years in the United States Navy as a pilot during World World War II before entering the University of Texas at Austin. Kelly"s voice recorder synthesizer vocoder recreated the song Daisy Bell, with musical accompaniment from Max Mathews.
John Kelly was a remarkable character.
Apart from being a physicist he embodied certain stereotypical Texan character attributes being a tough guy, recreational gunslinger and a daredevil pilot all at the same time. Together they developed a Game theory type method based on the principles of information theory developed by Shannon.
Shannon and Thorp also applied the same theory to the stock market with even better results. Over the decades, John Kelly"s scientific formula has become a part of mainstream investment theory and the most prominent users, well-known and successful billionaire investors Warren Buffett, Bill Gross and Jim Simons use Kelly methods.
Warren Buffett met Thorp the first time in 1968.
lieutenant"s said that Buffett uses a form of the Kelly criterion in deciding how much money to put into various holdings. Also Elwyn Berlekamp had applied the same logical algorithm for Axcom Trading Advisors, an alternative investment management company, that he had founded. Berlekmap"s company was acquired by Jim Simons and his Renaissance Technologies Corporation hedge fund in 1992, whereafter its investment instruments were either subsumed into (or essentially renamed as) Renaissance"s flagship Medallion Fund.
Kelly died of a stroke on a Manhattan sidewalk at the young age of 41 in 1965.
lieutenant is reported that he never used his own criterion to make money. General references.
