Born in Vienna in 1894, Frederick Mont, also known as A. F.  Mondschein or Frederick Mondschein or Adolf Fritz Mondschein, emigrated to the United States in the 1930s. Mont aka Mondschein owned the Galerie Sanct Lucas and counted among his clients many US museums. He had close relationships with American dealer Victor Spark (1898-1991) and the Newhouse Galleries. Mont played an important role in the transatlantic art trade. The names Mont, Mondschein, and Sanct Lucas appear in several artworks listed on NEPIP, the Nazi Era Provenance Research Portal.
