Rower Otto Maier won a gold medal at the 1912 Stockholm Olympics with the German coxed outriggers fours. He was one of two coxswains with the German rowing delegation in 1912. Maier never won a German Championship. He competed for Ruderclub Frankfurt 1865.
Karl Leister was the regular cox for Ludwigshafener Ruderverein and competed in the pre-Olympic races. It is often listed that both Maier and Leister participated in Stockholm, one serving as cox in round one, and then being replaced by the other for later rounds, although who started in round one was not certain. However, recent research using the Swedish Riksarkivet with the original results in the Olympic newspaper Olympiska Spelen Tidnings, and the German rowing journal, Wassersport, and with assistance by archivists at the Ludwigshafener Ruderverein and the Ruderclub Frankfurt 1865, makes it clear that Maier was the cox for all rounds for Ludwigshafener Ruderverein. It is not even certain that Leister was present in Stockholm.
