Interestingly, Robert Clary, the actor that played LeBeau spent WWII in Buchenwald and was the only member of his family to survuve the war. John Banner (Sgt. Shultz) was an Austrian Jew who had emmigrated to the US in the late 30s, but like Clary, had no relatives survive. Leon Askin (General Burkhalter) was also an Austrian Jew who fled Europe prior to the war.
