style was originally found in New York City in the late 19th century through the works of Richard Morris Hunt. Hunt was a renowned architect throughout the Northeast, particularly in New England and was one of the first American architects to study at the elite Ecole des Beaux-Arts in Paris, France. C.P.H. Gilbert was an apprentice of Hunt and emulated Hunt's classic Châteauesque style for the Warburg house while also adding some Gothic features. The original house is built in limestone with mansard roofs, dripping moldings, and gables. This architectural style was based on French revivalism and exuded wealth, a point which Felix Warburg wanted to make to his neighbors. It featured a green yard in front of the house, which was later converted into the museum's entrance. Renovations Once converted into a museum, the architect Kevin Roche, who also designed additions to the Metropolitan Museum of Art, was selected to design additions to the Jewish Museum. After $36 million, the development of 11,000 more square feet of exhibition space, and two and a half years, Roche finished his additions in June 1993. He intended his additions to be a continuation of the museum's Gothic revival features. This is especially clear in the Fifth Avenue facade and the auditorium. The Fifth Avenue facade, made of Indiana limestone, is carved in Gothic revival style. The auditorium is set in a retrofitted Gothic revival style ballroom and finds uses for the mansion's stained-glass dome and screen. The cafe in the basement has stained glass windows. Although these additions that were intended as a continuation of the museum's Gothic revival features, Roche also included additions that were meant to prevent the museum from appearing outdated and modernizing the facilities. For instance, Roche ensured that the education center and the auditorium would have the appropriate technology for their purposes, such as interactive visual displays. Collections The museum has nearly 30,000 objects including paintings, sculptures, archaeological artifacts, Jewish ceremonial art and many other pieces important to the preservation of Jewish history and culture. Artists included in the museum's collection include James Tissot, Marc Chagall, George Segal, Eleanor Antin and Deborah Kass. This represents the largest collection of Jewish art, Judaica and broadcast media outside of museums in Israel. It has a collection exhibition called Scenes from the Collection, which displays works of art from antiquity to the present. The museum's collection includes objects from ancient
