Anna Eleanor Roosevelt ' ( October 11, 1884 – November 7, 1962) was the longest-serving First Lady of the United States, holding the post from 1933 to 1945 during her husband President Franklin D. Roosevelt's four terms in office. President Harry S. Truman later called her the "First Lady of the World" in tribute to her human rights achievements.
A member of the Roosevelt and Livingston families, Eleanor had an unhappy childhood, suffering 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 feminist headmistress Marie Souvestre. Returning to the US, she married her fifth cousin, Franklin Delano Roosevelt, in 1905. The Roosevelts' marriage was complicated from the beginning by Franklin's controlling mother, Sara and after discovering Franklin's affair with Lucy Mercer in 1918, Eleanor resolved to seek fulfillment in a public life of her own. She persuaded Franklin to stay in politics following his partial paralysis from polio, and began to give speeches and campaign in his place. After Franklin's election as Governor of New York, Eleanor regularly made public appearances on his behalf. She had also shaped the role of First Lady during her tenure and beyond.
