Franz Nachtegall (1777 - 1847 A.D.) was an early proponent and directly responsible for introducing Physical Education in schools of Denmark.
Nachtegall was apparently stimulated or motivated to begin teaching gymnastics after reading the GutsMuths manual of gymnastics. During 1804 he was appointed as the first director of a Training School for the teaching of gymnastics to the army of Denmark. During 1807 he was appointed professor of gymnastics at Copenhagen University. Sometime shortly after 1814 he was appointed director of gymnastics for all of Denmark.
