Alan Lomax was an American ethnomusicologist, best known for his numerous field recordings of folk music during the 20th century. He was a musician, folklorist, archivist, writer, scholar, political activist, oral historian, and filmmaker. Lomax produced recordings, concerts, and radio shows in the U.S. and in England which played an important role in preserving folk music traditions in both countries and helped start both the American and British folk revivals of the 1940s, 1950s, and especially the early 1960s. He collected material first with his father, folklorist and collector John Lomax, and later, alone and with others. 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 on aluminum and acetate discs. After 1942, when Congress terminated the Library of Congress's funding for folk song collecting, Lomax continued to collect independently in Britain, Ireland, Caribbean region, Italy, Spain, and United States, using the latest recording technology, assembling an enormous collection of American and international culture.
