Little Walter, born Marion Walter Jacobs (May 1, 1930 – February 15, 1968), was an American blues harmonica player whose revolutionary approach to his instrument has earned him comparisons to Charlie Parker and Jimi Hendrix for innovation and impact on succeeding generations. His virtuosity and musical innovations fundamentally altered many listeners' expectations of what was possible on blues harmonica. Little Walter's body of work earned him a spot in The Rock and Roll Hall of Fame in 2008 making him the only artist ever to be inducted specifically for his work as a harmonica player.
