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.
Though widely respected in her later years, Roosevelt was a controversial First Lady for her outspokenness, particularly her stance on racial issues. She was the first presidential spouse to hold press conferences, write a syndicated newspaper column, and speak at a national 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.
