The Jewish Museum is an art museum and repository of cultural artifacts, housed at 1109 Fifth Avenue, in the former Felix M. Warburg House, along Museum Mile on the Upper East Side of Manhattan, New York City. The first Jewish museum in the United States, as well as the oldest existing Jewish museum in the world, it contains the largest collection of art and Jewish culture excluding Israeli museums, more than 30,000 objects. While its collection was established in 1904 at the Jewish Theological Seminary of America, the museum did not open to the public until 1947 when Felix Warburg's widow sold the property to the Seminary. It focuses both on artifacts of Jewish history and on modern and contemporary art. The museum's collection exhibition, Scenes from the Collection, is supplemented by multiple temporary exhibitions each year. History The collection that seeded the museum began with a gift of Jewish ceremonial art objects from Judge Mayer Sulzberger to the Jewish Theological Seminary of America on January 20, 1904, where it was housed in the seminary's library. The collection was moved in 1931, with the Seminary, to 122nd and Broadway. The Jewish Theological Seminary received over 400 Jewish ceremonial items and created, 'The Museum of Jewish Ceremonial Objects', previously the Jacob Schiff Library. The collection was subsequently expanded by major donations from Hadji Ephraim Benguiat and Harry G. Friedman. In 1939, in light of WWII, Poland sent about 350 objects to New York city from homes and synagogues in order to preserve them. Following Felix Warburg's death in 1937, in January 1944 his widow Frieda donated the family mansion to the seminary as a permanent home for the museum, and the site opened to the public as 'The Jewish Museum' in May 1947. Frieda Warburg said at the opening that the museum would not be a somber memorial, but rather a celebration of the Jewish faith and traditions. The first expansion of the museum was the addition of a sculpture garden in 1959 by Adam List. The building was expanded in 1963 and further by architect Kevin Roche in 1993. In the 1960s, the museum took a more active role in the general world of contemporary art, with exhibitions such as Primary Structures, which helped to launch the Minimalist art movement. In the decades since, the museum has had a renewed focus on Jewish culture and Jewish artists. From 1990 through
