Sam Salz was born on 12 March 1894 in Radomysl, Poland. He moved to Paris in the early 1920 to become an art student, but instead became a part of the local art dealing community. He worked with reknowned art dealer Ambroise Vollard [1867-1939] as well as buying directly from artists Derain, Vlaminck, Vuilllard and Bonnard. From 1926 until 1930 he worked as a dealer in Brussels, and returning to work in Paris and London until 1939, when he emigrated to the United States. In New York he continued to sell pictures to an elite clientele. The photographic archives of the National Gallery of Art has a collection of photographs from Sam Salz.
