Fritz Thiedemann (March 3, 1918 – January 8, 2000) was a German equestrian, considered to be one of the greatest show jumpers of his time.
Born in the town of Heide (Schleswig-Holstein), as the son of a farmer. His riding talents became clear at a young age, but he could not display them internationally until after World War II. During the war, Theidemann commanded a cavalry unit and was captured and interred at a Russian prison camp by war's end.
At the 1952 Olympics in Helsinki, Thiedemann achieved a unique performance, winning medals in two equestrian disciplines, a feat since unequalled. He placed third in the dressage team event, and won another bronze medal in the individual jumping contest with his favourite horse Meteor, with which he would win all major prizes in his career.
The following year, Thiedemann won a jumping silver at the World Championships in Paris. Winning another medal (bronze) in that event in 1956 in Aachen. That same year, he won a gold medal with the United Team of Germany in the 1956 Olympics in Stockholm, while just missing out on an individual medal with a fourth position.
