None of the above except Shaw are technology people. Simons is a mathematician, and Griffin seems to have a pure finance background: "While still at Harvard University, he started two funds from his dorm room, and he claims that in between classes he would make trades. He even installed a special satellite link to his dorm to acquire real-time market data. After graduating with a degree in economics, he won the attention of an investor named Frank C. Meyer, founder of Glenwood Capital [1]. Meyer was amazed at Griffin's success and rate of return with his investments (which at the time were largely based on convertible bonds), and provided a relatively small investment for Griffin to invest ($1 million) [2]. Griffin exceeded Meyer's expectations, and as word of his strong performance spread, investors persuaded to back Griffin. Citadel was officially founded Nov. 1, 1990 with $4.2 million; the name "Citadel" was chosen to suggest strength in times of volatility [3]." - http://en.wikipedia.org/wiki/Kenneth_C._Griffin http://en.wikipedia.org/wiki/Kenneth_C._Griffin
