Serge Sabarsky (born Siegfried Sabarsky; 1912-1996) was a prominent Austrian-American art dealer, collector, and historian specializing in early 20th-century German and Austrian Expressionist art. Born in Vienna, Austria-Hungary, he began his career in the vibrant cultural scene of interwar Vienna, working as a clown and set designer for the renowned cabaret Simplicissimus. In 1938, as a Jew fleeing the Nazi annexation of Austria, Sabarsky escaped first to Paris and then to New York in 1939, where he initially worked in various roles, including as an architectural designer after World War II. By the 1950s, Sabarsky had shifted his focus to art collecting and dealing, opening the Serge Sabarsky Gallery on Madison Avenue in 1968, which became a pivotal venue for German and Austrian Expressionism, featuring artists like Egon Schiele, Oskar Kokoschka, and Max Beckmann. He founded Galerie St. Etienne, further cementing his influence in promoting this niche. Sabarsky also taught classes on art dealing at New York University and collaborated with scholars and curators, though he emphasized direct aesthetic experience over academic analysis. His collection and gallery work significantly shaped the appreciation of Expressionist art in the United States. Sabarsky's life exemplified resilience and cultural entrepreneurship, bridging European modernism with American audiences until his death in 1996 at age 83.
