This large figural window became the central focus in the Chapel created in 1882 for the Association Residence for Respectable, Aged, Indigent Females on the upper west side of New York City. It is a memorial to Katherine Hinman Hamlin (1862–1903), secretary of the Association during her many years of service from 1877 until her death. Through Mrs. Hamlin’s careful recounting, the history of the Association’s great work was told. She was one of twelve charitable women who were honored for their service at the Association with a Tiffany Studios window. These windows were financed by their benefactrix, the reformer and women’s activist Mrs. Olivia Sage (1828–1918). Intended to serve as a respectable alternative to the unsavory “poorhouses” in lower Manhattan, the Association sought to create a residence that would physically and spiritually care for elderly women—many the widows of Union soldiers—in their final years. The choice of subject for the window spoke to the vital mission of the Association home—a responsibility to care for those abandoned. The scene represents the Biblical story of the banishment of Hagar and Ishmael from the house of Abraham at his wife Sarah’s command, and the appearance of an angel to Hagar in the desert serves as a reminder of their heavenly protection.
