9852 Gora           Discovered 1990 Dec. 24 by T. Seki at Geisei.
Ronald Gora (b. 1933) is a former American swimmer who finished eighth in the men's 100-meter free-style at the 1952 Helsinki Olympics. His remarkable sportsmanship impressed many when he disqualified himself by telling the officials of his own rule violation at a competition in Japan.
