Helen Adams Keller (June 27, 1880 â June 1, 1968) was an American author, political activist, and lecturer.
While she was there she had an operation on her eyes which allowed her to read normally for a limited amount of time. She stayed at Perkins for six years and graduated valedictorian of her class. Anne Sullivan Macy arrived in Tuscumbia, Alabama to be Helen Kellerâs teacher on March 3, 1887. She began spelling into Helenâs hand and after about a month Helen âmade contact with realityâ. When Helen was older she went to Radcliffe College. Anne âreadâ her all the texts that were not available in Braille.
