Viktor Matejka (4 December 1901 - 2 April 1993) was a Viennese politician and writer. He spent most of the Hitler years as a detainee at one of two concentration camps. In the summer of 1943 inmates at Dachau presented a satirical focusing on Adolf Hitler, watched by the camp's SS guards. The episode was described in his obituary, half a century later, as "probably the most dangerous stage performance in the world, as well as the most absurd". The leader of the improvised performance group was Viktor Matejka. Later he liked to assert that he had survived National Socialism through a blend of cunning and skill, which only the malicious and ignorant would have called "collaboration".
