Hungarian Expressionist artist Kadar achieved considerable international success in the 1920's and '30's, exhibiting his works in important galleries in Hungary, Berlin (Der Sturm Gallery), and New York (Brooklyn Museum). In 1937, his works were shown in the notorious exhibition of "Degenerate Art," in which the Nazis presented leading artists like Picasso and Ernst Ludwig Kirchner as exponents of "Jewish and Bolshevik" art.
With the German conquest of Hungary, Kadar found himself confined to a ghetto. He apparently worked as the assistant to the ghetto doctor, and drew annotated scenes of ghetto life on prescription forms. He died, forgotten, in Hungary after the war. His sketches were bought by Eliezer Rosenfeld, father of Zaki Rosenfeld, the present owner of the gallery. Zaki's mother, Sarah, translated Kadar's comments, and every page has been photographed so as to display the sketch and the comments alongside each other.
Kadar, considered one of the most significant revelations of European painting, explored the figure of the victim. He created powerful images based on Hungarian culture and legends. He experimented with a series of techniques from Futurism to Cubism. The drawings provide an extraordinary historical document recording the artist's experiences and the occurrences in the ghetto.
