McKinley Morganfield (April 4, 1913 – April 30, 1983), better known as Muddy Waters, was an American blues musician who is often cited as the "father of modern Chicago blues".
Muddy Waters grew up on Stovall Plantation near Clarksdale, Mississippi, and by age 17 was playing the guitar and the harmonica, emulating the local blues artists Son House and Robert Johnson. He was recorded in Mississippi by Alan Lomax for the Library of Congress in 1941. In 1943, he moved to Chicago to become a full-time professional musician. In 1946, he recorded his first records for Columbia Records and then for Aristocrat Records, a newly formed label run by the brothers Leonard and Phil Chess.
In the early 1950s, Muddy Waters and his band—Little Walter Jacobs on harmonica, Jimmy Rogers on guitar, Elgin Evans on drums and Otis Spann on piano—recorded several blues classics, some with the bassist and songwriter Willie Dixon. These songs included "Hoochie Coochie Man", "I Just Want to Make Love to You" and "I'm Ready". In 1958, he traveled to England, laying the foundations of the resurgence of interest in the blues there. His performance at the Newport Jazz Festival in 1960 was recorded and released as his first live album, At Newport 1960.
Muddy Waters' influence was tremendous, not just on blues and rhythm and blues but on rock and roll, hard rock, folk music, jazz, and country music. His use of amplification is often cited as the link between Delta blues and rock and roll.
