John Banner (Height: 6 feet 1 inch [1.85 meters]), born Johann Banner on January 28, 1910, was an Austrian-American actor who achieved lasting fame for his portrayal of the bumbling German Sergeant Hans Schultz in the beloved sitcom Hogan's Heroes (1965-1971).

Banner was born in Vienna, Austria-Hungary (now Ukraine). He studied acting at the prestigious Reinhardt Seminar and began his career on the Viennese stage. In 1938, with the rise of the Nazis, Banner, a Jew, fled Austria for the United States.

After arriving in America, Banner struggled to find work in his chosen profession. He took on odd jobs to make ends meet while continuing to pursue his passion for acting. Eventually, he began landing small roles in Hollywood films, often playing stereotypical Germans.

In 1965, Banner landed the role of Sergeant Schultz in the CBS sitcom Hogan's Heroes. The show was set in a German prisoner-of-war camp during World War II and followed the exploits of a group of American officers led by Colonel Robert Hogan (Bob Crane). Banner's portrayal of Schultz, the guard who was always "seeing nothing" and "hearing nothing" while the prisoners tunneled out of the camp or conducted other escapades, was a comedic highlight of the show.

Banner's comedic timing and delivery of the catchphrases "I see nothing!" and "I know nothing!" endeared him to audiences around the world. He remained with the show for its entire six-season run, becoming synonymous with the role of Sergeant Schultz.

After Hogan's Heroes ended in 1971, Banner continued to act, appearing in guest roles on various television shows. He also returned to the stage, performing in a number of productions.

In 1973, Banner died of a heart attack while visiting Vienna. He was 63 years old.
