George Kadish, born Zvi (Hirsh) Kadushin (1910 – September 1997), was a Lithuanian Jewish photographer who documented life in the Kovno Ghetto during the Holocaust, the period of the Nazi German genocide against Jews.
Prior to World War II he was a mathematics, science and electronics teacher at a Hebrew High School in Kovno, Lithuania.
During the period of Nazi control of Lithuania (along with indigenous Lithuanian collaborators) he successfully photographed various scenes of life and its difficulties in the ghetto in clandestine circumstances.
Kadish constructed cameras by which he could photograph through the buttonhole of his coat or over a window sill.
