Ott Jud was a 15th century German wrestling master. His name signifies that he was a Jew, and several of the versions of his treatise state that he was baptized Christian. Paulus Kal describes him as the wrestling master to the princes of Austria, and names him as a member of the Society of Liechtenauer. While Ott's precise lifetime is uncertain, he may have still been alive when Hans Talhoffer created the Gotha version of his manual in 1443, but certainly died some time before the creation of Codex Danzig in 1452.
Ott's treatise on grappling is repeated throughout all of the early German treatise compilations and seems to have become the dominant work on the subject within the Liechtenauer tradition.
