John Banner was an Austrian-born American actor, best known for his role as Sergeant Schultz in the situation comedy Hogan's Heroes (1965–1971). Schultz, constantly encountering evidence that inmates of his stalag were actively conducting anti-German espionage and sabotage activities, frequently feigned ignorance with the catchphrase, "I see nothing! I hear nothing! I know nothing!".

Hogan's Heroes is an American television sitcom set in a prisoner-of-war (POW) camp in Nazi Germany during World War II, which concerns a group of Allied prisoners who use the POW camp as an operations base for sabotage and espionage purposes directed against Nazi Germany. It ran for 168 episodes from September 17, 1965, to April 4, 1971, on the CBS network, the longest broadcast run for an American television series inspired by that war.
