Helen Adams Keller was a deafblind American author, activist and lecturer.

Helen Keller was born at an estate called Ivy Green in Tuscumbia, Alabama, on June 27, 1880, to parents Captain Arthur H. Keller, a former officer of the Confederate Army, and Kate Adams Keller, cousin of Robert E. Lee. The Keller family originates from Germany.

She was not born blind and deaf; it was not until nineteen months of age that she came down with an illness described by doctors as "an acute congestion of the stomach and the brain," which could have possibly been scarlet fever or meningitis. The illness did not last for a particularly long time, but it left her deaf and blind. At that time her only communication partner was Martha Washington, the 6-year old daughter of the family cook, who was able to create a sign language with Helen, so that by age seven, she had over sixty different signs to communicate with her family. In his doctoral dissertation, Soviet blind-deaf psychologist A. Meshcheryakov stated that Martha's friendship and teaching was crucial for Helen's later developments.
