One of the oldest American foundations, the Russell Sage Foundation was established in 1907 for "the improvement of social and living conditions in the United States" by a gift of $10 million from Margaret Olivia Slocum Sage (1828–1918), widow of railroad magnate and financier Russell Sage. Mrs. Sage directed the foundation to pursue its mission through a broad set of activities, including "research, publication, education, the establishment and maintenance of charitable or benevolent activities, agencies and institutions, and the aid of any such activities, agencies, or institutions already in existence."
