Helen Adams Keller 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, Annie 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 known worldwide through the dramatic depictions of the play and film The Miracle Worker.

A prolific author, Keller was well traveled and was outspoken in her opposition to war. She campaigned for women's suffrage, workers' rights, and socialism, as well as many other progressive causes.

Keller devoted much of her later life to raising funds for the American Foundation for the Blind. On September 14, 1964, President Lyndon B. Johnson awarded Helen Keller the Presidential Medal of Freedom, one of the United States' highest two civilian honors.
