Helen Adams Keller was an American author, political activist, and lecturer. She was the first deaf-blind 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. A prolific author, Keller was well-traveled and outspoken in her convictions. A member of the Socialist Party of America and the Industrial Workers of the World, she campaigned for women's suffrage, labor rights, socialism, antimilitarism, and other similar causes. She was inducted into the Alabama Women's Hall of Fame in 1971 and was one of twelve inaugural inductees to the Alabama Writers Hall of Fame on June 8, 2015. Helen proved to the world that deaf people could all learn to communicate and that they could survive in the hearing world. She also taught that deaf people are capable of doing things that hearing people can do. She is one of the most famous deaf people in history and she is an idol to many deaf people in the world.
