Günter Bergau was a rower who finished seventh both with the coxed pairs at the 1964 Tokyo Olympics for the mixed German team together with Peter Gorny and cox Karl-Heinz Danielowski, and with the eights at the 1968 Mexico City Olympics, then representing East Germany. Both boats missed the final and won the B-finals. The coxed pairs were also the 1964 European Champions, adding a silver medal in 1967. They also won East German titles from 1963-65. Bergau and Gorny had already won the title with non-Olympian Bernd Giza in 1962, and both also claimed one more national championship in 1965 with the coxed fours.
