Marion Walter Jacobs (May 1, 1930 – February 15, 1968), known as Little Walter, was an American blues musician, singer, and songwriter, whose revolutionary approach to the harmonica and impact on succeeding generations earned him comparisons to such seminal artists as Django Reinhardt, Charlie Parker and Jimi Hendrix. His virtuosity and musical innovations fundamentally altered many listeners' expectations of what was possible on blues harmonica. He was inducted into The Rock and Roll Hall of Fame in 2008 in the category Sideman, the only artist to be inducted specifically as a harmonica player.
