There’s a youtube video of Pat interviewing Werner Klemperer(Colonel Klink) that I watched from his show.
Werner Klemperer’s cousin Victor Klemperer wrote “The language of the 3rd Reich” about how the nazis manipulated the German language to make fascism more palatable to Germany. V Klemperer remained a “free” Jew in nazi Germany due to the fact that he was married to a wealthy and influential socialite. It also helped that he lived under virtual house arrest until he and his wife fled the bombing of Dresden.
Composer / conductor Otto Klemperer was another family member.
