The Blomberg–Fritsch affair began soon after the marriage on 12 January 1938 of the War Minister Werner von Blomberg to Erna Gruhn, when the Berlin police discovered she had a long criminal record and had posed for pornographic photographs. According to testimony given much later, at the Nuremberg trials, information received by the Police Commissioner within days also indicated that "Marshal von Blomberg's wife had been a previously convicted prostitute who had been registered as a prostitute in the files of seven large German cities; she was in the Berlin criminal files. ... She had also been sentenced by the Berlin courts for distributing indecent pictures."
