Friedrich Heinrich Zinckgraf (30 October 1878 – 7 June 1954) was a German gallery owner, art dealer and philatelist from Munich involved in the Aryanisation of the Jewish-owned Heinemann Gallery[1][2] and in selling Nazi-looted art,[3][4] notably for Hitler's planned Linz museum.
[5] After World War II he was a supporter of the philatelistic department of the Munich City Library.
In 1939 he acquired the gallery through Aryanization after the Jewish owner Mrs. Franziska Heinemann had been imprisoned for some weeks by the Nazis.
Two years after his death, the city of Munich dedicated a street to him in the Großhadern quarter.
In 2005 Heinrich von Zügel's ZWEI RINDER AUF DER WEIDE (Two Cows in a Meadow) which had been seized by the Nazis and sold via Zinckgraf in a forced sale, was restituted to the heirs of the Jewish art collector Alexander Lewin.
