The Russell Sage Foundation was established by Margaret Olivia Sage in 1907 for "the improvement of social and living conditions in the United States." The foundation supports visiting scholars in residence and publishes books and a journal under its own imprint. It also funds researchers at other institutions and supports programs intended to develop new generations of social scientists. The Pipeline Grants, initially co-funded with the Economic Mobility and Opportunity program at the Bill & Melinda Gates Foundation, support early-career scholars and promotes diversity in the social sciences. They were renamed the Sheldon Danziger Pipeline Grants in 2025.
