Munzer was a professor of economics and a believing Catholic; he was acquainted with both Georg Moenius and Hermann Borchardt, who were friends of Werfel. The correspondence constitutes the first contact between Munzer and Werfel; it appears that they never had the chance to meet in person. According to notes recorded by Falkenberg after a conversation with Egbert Munzer's widow, Munzer was born in Bavaria in 1898, emigrated to Canada in 1940, and died in Quebec in 1948. Falkenberg was the chief editor (Cheflektor) at S. Fischer Verlag, which was Werfel's German publisher.
