Justin 
K. Thannhauser was the son of renowned art dealer Heinrich Thannhauser, 
who founded the Galerie Moderne in Munich in 1909. From an early age, 
Thannhauser worked with his father to build impressive exhibitions of 
Impressionist and Post-Impressionist works as well as the art of the 
contemporary French and German avant-gardes. The Thannhausers’ 
commitment to promoting artistic progress paralleled the vision of 
Solomon R. Guggenheim. In recognition of this shared spirit, Justin 
Thannhauser bequested a significant portion of his art 
collection—including masterpieces by Cézanne, Gauguin, Manet, Monet, 
Picasso, Pissarro, Renoir, and Van Gogh—to the Guggenheim Museum, where 
it is on view in a dedicated gallery.
