Eleanor Roosevelt 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.
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 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.
