Marjory Logan Gengler Smith is an American retired tennis player. In 1973, while a student at Princeton University, she was captain of the women's tennis team and led them to an undefeated season in 1972. She was the top ranked player at Princeton, the number one-ranked female player in the Eastern United States, and the first woman to be featured, as "Princeton's Best Athlete", on the cover of "Princeton Alumni Weekly". In 1973, inspired by the Battle of the Sexes between Billie Jean King and Bobby Riggs, Gengler took on Jeffrey Lewis-Oakes, the top ranked men's junior varsity player, but lost the match. Gengler competed at the US Open in mixed doubles in 1971, 1973, and 1974 and in doubles in 1971, as well as singles in 1968, 1969, 1970, and 1971. She also competed at Wimbledon in mixed doubles in 1972. She was inducted into the International Tennis Hall of Fame in 2004. Gengler is married to retired professional tennis player Stan Smith.
