Answer by taking a quote from the following article:

Louis Thomas Hardin (May 26, 1916 - September 8, 1999), also known as Moondog, was an American musician, composer, theoretician, poet and inventor of several musical instruments. He was blind from the age of 16. Hardin lived in New York from the late 1940s until 1972, and during this time he could often be found on 6th Avenue, between 52nd and 55th Streets, wearing a cloak and a horned helmet sometimes busking or selling music, but often just standing silently on the sidewalk. He was widely recognized as "the Viking of 6th Avenue" by thousands of passersby and residents who weren't aware of his musical career.

Born to an Episcopalian family in Marysville, Kansas, Hardin started playing a set of drums that he made from a cardboard box at the age of five. His family relocated to Wyoming and his father opened a trading post at Fort Bridger. He attended school in a couple of small towns. At one point, his father took him to an Arapaho Sun Dance where he sat on the lap of Chief Yellow Calf and played a tom-tom made from buffalo skin.  Hardin played drums for the high school band in Hurley, Missouri before losing his sight at the age of 16 in a farm accident on July 4, 1932, involving a dynamite cap. After learning the principles of music in several schools for blind young men across middle America, he taught himself the skills of ear training and composition. He studied with Burnet Tuthill and at the Iowa School for the Blind.  He then moved to Batesville, Arkansas where he lived until 1942, when he got a scholarship to study in Memphis, Tennessee. Although the majority of his musical training was self-taught by ear, he learned some music theory from books in braille there.  In 1943 Hardin moved to New York, where he met noted classical music luminaries such as Leonard Bernstein and Arturo Toscanini, as well as legendary jazz performer-composers such as Charlie Parker and Benny Goodman, whose upbeat tempos and often humorous compositions would influence Hardin's later work. One of his early street posts was near the famed 52nd Street nightclub strip, and he was well-known to many jazz musicians and fans. By 1947 Hardin had adopted the name "Moondog" in honor of a dog "who used to howl at the moon more than any dog I knew of".
