Americans still remember the wife of President Franklin Delano Roosevelt. She took an active role in the American public life. Eleanor Roosevelt was born in New York in 1884. She had a lonely childhood. Though her family was well-known in America, her uncle Theodore Roosevelt was the 26th president of the United States, she personally felt very unhappy. Once Eleanor said that she was the “ugly duckling” in a family of beautiful people. Her mother called her “granny” because she was very serious and never smiled. She loved her parents very much but her father made her life miserable. He had a drinking problem and spent much time in hospital.

When Eleanor was 15 she went to England to study in an English school. After her return to New York she was a teacher for a short time. At that time Eleanor began the social activities that would make her so famous. Her husband, F. D. Roosevelt, became president in 1932. By that time Eleanor had become known in the USA for her social work. She didn’t stop her activities and continued them after the death of her husband in 1945. Her years alone were active and productive years. Not only in the United States, but in countries around the world, she was a symbol for hope and help. переведите плизз))
