Description

The Felix M. Warburg House is a mansion at 1109 Fifth Avenue on the Upper East Side of Manhattan in New York City. The house was built from 1907 to 1908 for the German-American Jewish financier Felix M. Warburg and his family. After Warburg's death in 1937, his widow sold the mansion to a real estate developer. When plans to replace the mansion with luxury apartments fell through, ownership of the house reverted to the Warburgs, who then donated it in 1944 to the Jewish Theological Seminary of America. In 1947, the Seminary opened the Jewish Museum of New York in the mansion. The house was named a New York City designated landmark in 1981 and was added to the National Register of Historic Places in 1982.
