Helen Adams Keller (June 27, 1880 – June 1, 1968) 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 Keller and her teacher, Anne Sullivan, was made famous by Keller's autobiography, The Story of My Life, and its adaptations for film and stage, The Miracle Worker. Her birthplace in West Tuscumbia, Alabama, is now a museum and sponsors an annual "Helen Keller Day". Her June 27 birthday is commemorated as Helen Keller Day in Pennsylvania and, in the centenary year of her birth, was recognized by a presidential proclamation from US President Jimmy Carter.

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
