Photograph, 9 Lexington Avenue, New York, New York

The Cooper-Hewitt family lived together at 9 Lexington Avenue near Gramercy Park in New York City. The house contained 35 rooms, including a large library and gymnasium. In 1883, architect Stanford White renovated the mansion to include a new music room and private theater. The Hewitts appeared in the newspapers and magazines for their at-home musicales, clever costume suppers, and dances with imaginative themes.

Sarah and Eleanor were strongly influenced by their family, following similar passions in education, philanthropy, and art. They also shared the family's anti-women's suffrage stance in the decades leading up to the passage of the 19th Amendment, which guaranteed women the same right to vote as men.

This object was previously on display as a part of the exhibition Sarah & Eleanor Hewitt: Designing a Modern Museum.
