Born in Berlin, Germany into a non-observant Jewish family, the son of a prosperous banker, he converted to Christianity in his late teens, and thereafter the interpretation and reinterpretation of Christianity was a consistent theme in his writings. He met and married Margrit Hüssy in 1914. In 1925, the couple legally combined their names. They had a son, Hans, in 1921.
Eugen Rozvan was a Hungarian-born Romanian communist activist, lawyer, and Marxist historian, who settled in the Soviet Union late in his life and was executed during the Great Purge.
