Alan Lomax was an American ethnomusicologist and folklorist known for his extensive collection of field recordings of folk music from the 20th century. He produced recordings, concerts, and radio shows in both the US and England, which played a significant role in preserving folk music traditions in both countries, and helped start both the American and British folk revivals of the 1940s, 1950s, and early 1960s. Lomax recorded thousands of songs and interviews for the Archive of American Folk Song, of which he was the director, at the Library of Congress. He is credited with discovering and bringing to a wider audience many notable musicians, including Robert Johnson, Woody Guthrie, Pete Seeger, Burl Ives, Lead Belly, and Muddy Waters.
