See for a contemporary report of Hirsch's work and an interview about his Jewish name and background:
J. Gompers, ‘Bij Fritz Hirsch op bezoek. Een interview’ in: De Vrijdagavond 3(1926), nr. 43: dl. 2, 264-267.
In the media resource centre of the Jewish Historical Museum is a textbook of one of Hirsch's operettas: 'Wir walzen in den Himmel hinein'.
At the 10th jubilee of the Fritz Hirsch Operette Gezelschap the book 10 jaar Fritz Hirsch operette in Nederland was published.
There are still recordings of the company.
