Jahnâs techniques became so popular that his gymnastics techniques were adopted by the US military toward the end of the 19th century to improve hand-to-hand combat skills. Gymnastics earned a spot in the first summer Olympic games in 1896 and has been an Olympic sport ever since.
Jahn invented several of the apparatuses that would be the basis of modern equipment. Thus in the history of gymnastics, he is considered as its father. Among these inventions were the ring, pommel horse, and the vault. The balance beam, the parallel bars and the horizontal bar were also developed along this period.
