オットー・シュトラッサー
Shortly after arriving in Prague, Hirsch became involved in the Black Front, a nationalist group of anti-Hitler German expatriates who advocated Strasserism. He was encouraged to introduce himself to its head, Otto Strasser, by his mentor, Tusk (Eberhard Köbel). Tusk had been a leader of "Deutsche Jungenschaft", a branch of the German youth movement "(Bündische Jugend") to which Hirsch belonged. The "Jungenschaft" itself was outlawed in 1935 and Tusk escaped arrest by fleeing to London.
