Kenneth Saul Rogoff learned chess from his father at age six, but only took up the game in earnest when he received a chess set for his 13th birthday. He was soon recognised as a chess prodigy. By age 14, he was a USCF master and New York State Open Champion, and shortly thereafter became a senior master, the highest US national title. At sixteen, Rogoff dropped out of high school to concentrate on chess, and spent the next several years living primarily in Europe and playing in tournaments there. When eighteen, he made the decision to go to college and pursue a career in economics rather than to become a professional player, although he continued to play and improve for several years afterward. Rogoff was awarded the IM title in 1974 and the GM title in 1978. He came third in the World Junior Championship of 1971 and finished second in the US Championship of 1975, which doubled as a Zonal competition, one-half point behind Walter Shawn Browne; this result qualified him for the 1976 Interzonal at Biel, where he finished 13-15th. In other tournaments he finished equal first at Norristown 1973 and Orense 1976.
Early in his economics career, Rogoff served as chief economist at the International Monetary Fund and also at the Board of Governors of the Federal Reserve System. He is currently the Thomas D. Cabot Professor of Public Policy and Professor of Economics at Harvard University.
