Kenneth Cordele Griffin (born October 15, 1968) is an American hedge fund manager. He is the founder and CEO of Citadel LLC, a Chicago-based investment firm. Citadel’s group of hedge funds rank among the largest and most successful in the world. In 1986, Griffin started to invest during his freshman year at Harvard University after reading a Forbes magazine article. During his second year at Harvard, he started a hedge fund focused on convertible bond arbitrage. The fund was capitalized with $265,000 from friends and family, including money from his grandmother. He installed a satellite link to his dorm to acquire real-time market data. The investment strategy helped preserve capital during the stock market crash of 1987. Griffin’s early success enabled him to launch a second fund, and between the two funds he was managing just over $1 million. Griffin graduated from Harvard in 1989 with a degree in economics. After graduating from Harvard, Frank C. Meyer, an investor and founder of Glenwood Capital LLC, provided Griffin with $1 million to invest. Griffin founded Citadel in 1990 with $4.6 million.
