Helen Keller (1880-1968)
Helen Keller was a prolific American author and a political and disability rights activist. When she was a toddler, Helen lost her sight and hearing. With the help of her teacher Anne Sullivan - who remained Helen's companion throughout her life - Helen Keller learned language in all its forms and went on to write multiple books on a variety of subjects. She spoke on a number of causes, the most prominent of which were her campaigns for disabilities and women's suffrage.
Over her lifetime, Helen Keller wrote 14 books and many speeches. The Frost King, which was her first-ever published work at the age of 11, was alleged to have been plagiarized from another book by Margaret Canby, The Frost Fairies. But it was later revealed that she had experienced cryptomnesia, a condition where one knows something by memory but forgets that they know about it. Her autobiography, The Story of My Life, was published in 1903 and remains her most famous work, chronicling her life up to the age of 22. Her other works span across a variety of subjects, ranging from socialism in Out of the Dark (1913) and her religious and spiritual journey in Light in My Darkness (1927) to her general thoughts about the world in The World I Live In (1908).
