Alan Lomax was one of the great American field collectors of folk music of the 20th century. He was also a folklorist, ethnomusicologist, archivist, writer, scholar, political activist, oral historian, and film-maker. Lomax also produced recordings, concerts, and radio shows in the US and in England, which played an important role in both the American and British folk revivals of the 1940s, '50s and early '60s. During the New Deal, with his father, famed folklorist and collector John A. Lomax and later alone and with others, Lomax recorded thousands of songs and interviews for the Archive of American Folk Song at the Library of Congress on aluminum and acetate discs.
After 1942, when Congress cut off the Library of Congress's funding for folk song collecting, Lomax continued to collect independently in Britain, Ireland, the Caribbean, Italy, and Spain, as well as the United States, using the latest recording technology, assembling an enormous, comprehensive collection of American and international culture. With the start of the Cold War, Lomax continued to speak out for a public role for folklore, even as academic folklorists turned inward.
