Anna Eleanor Roosevelt (; October 11, 1884 – November 7, 1962) was an American politician, diplomat and activist. She was the longest-serving First Lady of the United States, having held the post from March 1933 to April 1945 during her husband President Franklin D. Roosevelt's four terms in office, and 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.
Roosevelt was a member of the prominent American Roosevelt and Livingston families and a niece of President Theodore Roosevelt. She had an unhappy childhood, having suffered the deaths of both parents and one of her brothers at a young age. At 15, she attended Allenwood Academy in London and was deeply influenced by its feminist headmistress Marie Souvestre. Returning to the U.S., she married her fifth cousin once removed, Franklin Delano Roosevelt, in 1905. The Roosevelts' marriage was complicated from the beginning by Franklin's controlling mother, Sara, and after Eleanor discovered her husband's affair with Lucy Mercer in 1918, she resolved to seek fulfillment in a public life of her own. She persuaded Franklin to stay in politics after he was stricken with debilitating polio in 1921, which cost him the normal use of his legs, and Roosevelt began giving speeches and appearing at campaign events in his place. Following Franklin's election as Governor of New York in 1928, and throughout the remainder of Franklin's public career in government, Roosevelt regularly made public appearances on his behalf, and as First Lady while her husband served as President, she significantly reshaped and redefined the role of that office during her own tenure and beyond, for future First Ladies.
Though widely respected in her later years, Roosevelt was a controversial First Lady at the time for her outspokenness, particularly her stance on racial issues. She was the first presidential spouse to hold regular press conferences, write a daily newspaper column, write a monthly magazine column, host a weekly radio show, and speak at a national party convention. On a few occasions, she publicly disagreed with her husband's policies. She launched an experimental community at Arthurdale, West Virginia, for the families of unemployed miners, later widely regarded as a failure. She advocated for expanded roles for women in the workplace, the civil rights of African Americans and Asian Americans, and the rights of World War II refugees.
Following her husband's death in 1945, Roosevelt remained active in politics for the remaining 17 years of her life. She pressed the United States to join and support the United Nations and became its first delegate. She served as the first chair of the UN Commission on Human Rights and oversaw the drafting of the Universal Declaration of Human Rights. Later she chaired the John F. Kennedy administration's Presidential Commission on the Status of Women. By the time of her death, Roosevelt was regarded as "one of the most esteemed women in the world"; she was called "the object of almost universal respect" in her New York Times obituary. In 1999, she was ranked ninth in the top ten of Gallup's List of Most Widely Admired People of the 20th Century.
She is also known as Anna Eleanor Roosevelt.
In April 1960, Roosevelt was diagnosed with aplastic anemia soon after being struck by a car in New York City. In 1962, she was given steroids, which activated a dormant case of tuberculosis in her bone marrow, and she died of resulting cardiac failure at her Manhattan home at 55 East 74th Street on the Upper East Side on November 7, 1962, at the age of 78. Her daughter Anna took care of Roosevelt when she was terminally ill in 1962. President John F. Kennedy ordered all United States flags lowered to half-staff throughout the world on November 8 in tribute to Roosevelt.
Among other prominent attendees, President Kennedy and former presidents Truman and Eisenhower honored Roosevelt at funeral services in Hyde Park on November 10, 1962, where she was interred next to her husband in the Rose Garden at "Springwood", the Roosevelt family home. At the services, Adlai Stevenson said: "What other single human being has touched and transformed the existence of so many?", adding, "She would rather light a candle than curse the darkness, and her glow has warmed the world."
After her death, her family deeded the family vacation home on Campobello Island to the governments of the U.S. and Canada, and in 1964 they created the 2,800-acre (11 km2) Roosevelt Campobello International Park.
