Marion Walter Jacobs (May 1, 1930 – February 15, 1968), known as Little Walter, was an American bluesmusician, singer, and songwriter, whose revolutionary approach to the harmonica had a strong impact on succeeding generations, earning 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, the first and, to date, only artist to be inducted specifically as a harmonica player.

Jacobs’ date of birth is usually given as May 1, 1930, in Marksville, Louisiana. He was born without a birth certificate and when he applied for a Social Security card in 1940, his birthdate was listed as May 1, 1923. Over the years he often gave different years, but May 1 was constant. In some other documents he filled out before reaching the age of majority he indicated birth years of 1925 and 1928, probably to appear to be of legal age to sign contracts for recordings and club work.
