The Heinemann Gallery, a Munich art dealership founded in 1872, was Aryanized under the Nazis by Friedich Heinrich Zinckgraf.
[1] The art dealership had branches in Frankfurt am Main, Nice and New York, with numerous exhibitions in 19th century and French painting in particular.
[2] After Theobald's death in 1929, the latter's widow, Franziska Heinemann (1882–1940), daughter of Joseph Schülein, took over the gallery together with her son Fritz (1905–1983) until it was expropriated by Nazis at the end of 1938.
With the help of a large loan of 275,000 Reichsmarks from his friend, the powerful financier Hjalmar Schacht, Zinckgraf was able to carry out this Aryanization at the end of 1939.
[7] Zinckgraf became the official owner of the Heinemann gallery,[8] with Hjalmar Schacht as silent partner (40% share of future profits).
