9999 Wiles           Discovered 1973 Sept. 29 by C. J. van Houten and I. van Houten-Groeneveld on Palomar Schmidt plates taken by T. Gehrels.
Named in honor of Andrew J. Wiles (b. 1953), British mathematician world-renowned for his 1993 proof of Fermat's Last Theorem, one of the most difficult mathematical problems, which had remained unsolved for more than 350 years. A gap in the proof was closed by Wiles in 1994. His achievement came too late for him to receive the Field Medal, because Wiles was then over the age limit of 40. The International Mathematical Union therefore gave him its most prestigious award, the Silver Plaque. Wiles' fields of research are number theory and arithmetic geometry. He is a professor at Princeton University.
