Manfred Steinbach
Manfred Steinbach is a German former sprinter, long jumper, professor of sport medicine and government official. He competed at the 1956 Summer Olympics in the 100 m, but failed to reach the final. In 1960 he finished in fourth place in the long jump, setting his personal best at 8.00 m. Shortly before the Olympics, in July 1960 he jumped 8.14 m,cm above the 1935 record by Jesse Owens, but this jump was discounted because of lacking wind measurement. He set another, officially recognized world record in August 1958, by running the 4100 m relay in 39.5 seconds together with Martin Lauer, Heinz Ftterer and Manfred Germar.
Steinbach was born and raised in East Germany, but in April 1958 fled to West Germany, following his parents who did so in 1953. After that his coach was accused of complicity and imprisoned.
