LOUISVILLE, Ky. -- A piece of American history is on display in Louisville.
Helen Keller's writing desk was unveiled at the American Printing House for the Blind Museum.
Keller was the first person who was deaf-blind to earn a college degree, and was a well-published author, lecturer and political activist.
The desk is on loan from the American Foundation for the Blind, where Keller worked for 44 years.
The APH Museum is free to the public.
