Moondog

"Moondog was the pseudonym of Louis Thomas Hardin (May 26, 1916 – September 8, 1999), a blind American composer, musician, cosmologist, poet, and inventor of several musical instruments. Although these achievements would have been considered extraordinary for any blind person, Moondog further removed himself from society through his decision to make his home on the streets of New York for approximately twenty of the thirty years he spent in the city."
