Heinrich Thannhauser (born February 16, 1859, in Hürben, today a district of Krumbach (Swabia); died 1934 on the German-Swiss border) was a German gallery owner and art collector.
[1] At first he exhibited the artworks of French Impressionists such as Édouard Manet, Edgar Degas and Paul Gauguin.
[3] In 1918 he had himself painted in Berlin simultaneously by Lovis Corinth and by Max Liebermann; the one he sat for a portrait in the morning, the other in the afternoon.
His son Justin Thannhauser, who was also an art dealer, established branches in Lucerne (1919) and Berlin (1927).
In 1963 Justin Thannhauser donated his private collection as well as that of his father, Heinrich, to the Guggenheim Museum, New York, where a room commemorates him.
