Acquavella Galleries is distinguished for its expertise in the fields of 19th, 20th, and 21st century art. Founded by Nicholas Acquavella in the early 1920s, the gallery is now a three-generation, family-owned business: Bill Acquavella joined his father in 1960, his daughter Eleanor joined in 1997, and sons Nick and Alexander followed in 2000 and 2003. The gallery first specialized in works of the Italian Renaissance and old master paintings before expanding to the masters of Impressionism, Post-Impressionism, Cubism, and Surrealism, and since the late 1980s has also dealt in postwar and contemporary art from its Upper East Side townhouse at 18 East 79th Street.
