Karl Thieme

Karl Otto Thieme (May 25, 1902—July 26, 1963) was a German historian and political scientist. Thieme converted to the Catholic Church from Lutheranism and was part of an international intellectual network, along with figures such as Waldemar Gurian and John M. Oesterreicher (both converts from Judaism), who initially argued against anti-Jewish sentiment and for Jewish conversion to Christianity. After the Second World War, he was a pioneer in Catholic-Jewish interfaith dialogue through his work at Gertrud Luckner's ''Freiburger Rundbrief'' and numerous personal correspondencies. Although Thieme died before the end of the Second Vatican Council, his activities, along with "his intellectual sparring partner" Oesterreicher, paved the way for ''Nostra aetate'' (Declaration on the Relation of the Church with Non-Christian Religions).
