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 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.

A few months after returning from his second European tour, Little Walter was involved in a fight while taking a break from a performance at a nightclub on the South Side of Chicago. He apparently sustained only minor injuries in this altercation, but they aggravated the damage he had suffered in previous violent encounters, and he died in his sleep at the apartment of a girlfriend, at 209 East 54th Street in Chicago, early the following morning. The official cause of death on his death certificate was coronary thrombosis (a blood clot in the heart). Evidence of external injuries was so insignificant that the police reported that his death was due to “unknown or natural causes”, and no external injuries were noted on the death certificate. His body was buried at St. Mary’s Cemetery, in Evergreen Park, Illinois, on February 22, 1968.
