Anna Eleanor Roosevelt (; October 11, 1884 - November 7, 1962) was an American politician, diplomat and activist. She served as the First Lady of the United States from March 1933 to April 1945 during her husband President Franklin D. Roosevelt's four terms in office, making her the longest serving First Lady of the United States.  Roosevelt served as United States Delegate to the United Nations General Assembly from 1945 to 1952. President Harry S. Truman later called her the "First Lady of the World" in tribute to her human rights achievements.

In 1972, the Eleanor Roosevelt Institute was founded; it merged with the Franklin D. Roosevelt Four Freedoms Foundation in 1987 to become the Roosevelt Institute. The Roosevelt Institute is a liberal American think tank. The organization, based in New York City, states that it exists "to carry forward the legacy and values of Franklin and Eleanor Roosevelt by developing progressive ideas and bold leadership in the service of restoring America's promise of opportunity for all."  Eleanor Roosevelt High School, a public magnet high school specializing in science, mathematics, technology, and engineering, was established in 1976 at its current location in Greenbelt, Maryland. It was the first high school named for Eleanor Roosevelt, and is part of the Prince George's County Public Schools system.  Eleanor lived in a stone cottage at Val-Kill, which was two miles east of the Springwood Estate. The cottage had been her home after the death of her husband and was the only residence she had ever personally owned. In 1977, the home was formally designated by an act of Congress as the Eleanor Roosevelt National Historic Site, "to commemorate for the education, inspiration, and benefit of present and future generations the life and work of an outstanding woman in American history." In 1998, Save America's Treasures (SAT) announced Val-Kill cottage as a new official project. SAT's involvement led to the Honoring Eleanor Roosevelt (HER) project, initially run by private volunteers and now a part of SAT. The HER project has since raised almost $1 million, which has gone toward restoration and development efforts at Val-Kill and the production of Eleanor Roosevelt: Close to Home, a documentary about Roosevelt at Val-Kill. Due in part to the success of these programs, Val-Kill was given a $75,000 grant and named one of 12 sites showcased in Restore America: A Salute to Preservation, a partnership between SAT, the National Trust and HGTV. The Roosevelt Study Center, a research institute, conference center, and library on twentieth-century American history located in the twelfth-century Abbey of Middelburg, the Netherlands, opened in 1986. It is named after Eleanor Roosevelt, Theodore Roosevelt, and Franklin Roosevelt, all of whose ancestors emigrated from Zeeland, the Netherlands, to the United States in the seventeenth century.  In 1988, Eleanor Roosevelt College, one of six undergraduate residential colleges at the University of California, San Diego, was founded. ERC emphasizes international understanding, including proficiency in a foreign language and a regional specialization. Eleanor Roosevelt High School, a small public high school on the Upper East Side of Manhattan in New York City, was founded in 2002. Eleanor Roosevelt High School in Eastvale, California, opened in 2006.
