However. he remained with the club as a youth coach.
Reading in a newspaper on 10 April 1933 that all Southern German clubs would ban Jewish members, he left KFV by his own choice after over 30 years as a member. In a letter to his club he requested that it should not be forgotten that, even though Jews were now the whipping boys of the nation, many of them had given their life blood for the German nation and were true patriots, as shown by their deeds and words.
Hirsch was the first Jewish player to represent the German national team. Hirsch had served for four years in the German Army in World War I, and had been decorated with the Iron Cross. His brother Leopold died in action in 1916, also serving in the German Army.
