Rower Sibylle Reinhardt was on the gold medal-winning East German coxed quadruple sculls crew at the 1980 Moskva Summer Olympics. As a 16-year-old she had already won the world title in the same class under her birth name Tietze, and in 1975 she won the East German national title. Reinhardt was then nominated for the 1976 Montréal Games, but only as a substitute. In 1977 and 1979 she won both the national and world titles in the coxed quadruple sculls.
Reinhardt later studied art and became a freelanced artist and art teacher. In 2008, she published an autobiography entitled Schattengold, explaining that she had never taken doping substances during her sports career, and was never a member of a political party in former GDR.
