Helen Adams Keller (June 27, 1880 – June 1, 1968) was an American author, political activist, and lecturer. She was the first deafblind person to earn a bachelor of arts degree. The story of how Keller's teacher, Anne Sullivan, broke through the isolation imposed by a near complete lack of language, allowing the girl to blossom as she learned to communicate, has become widely known through the dramatic depictions of the play and film The Miracle Worker. Her birthplace in West Tuscumbia, Alabama, is now a museum and sponsors an annual "Helen Keller Day". Her birthday on June 27 is commemorated as Helen Keller Day in the U.S. state of Pennsylvania and was authorized at the federal level by presidential proclamation by President Jimmy Carter in 1980, the 100th anniversary of her birth.
