Alan Lomax (January 31, 1915 – July 19, 2002) was an American field collector of folk music of the 20th century. He was also a folklorist, ethnomusicologist, archivist, writer, scholar, political activist, oral historian, and film-maker. Lomax 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, 1950s and early 1960s. He collected material first with his father, 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, of which he was the director, 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 collection of American and international culture. In March 2004 the material captured and produced without Library of Congress funding was acquired by the Library, which 'brings the entire seventy years of Alan Lomax's work together under one roof at the Library of Congress, where it has found a permanent home.' With the start of the Cold War, Lomax continued to speak out for a public role for folklore, even as academic folklorists turned inward. He devoted much of the latter part of his life to advocating what he called Cultural Equity, which he sought to put on a solid theoretical foundation through to his Cantometrics research (which included a prototype Cantometrics-based educational program, the Global Jukebox). In the 1970s and 1980s Lomax advised the Smithsonian Institution's Folklife Festival and produced a series of films about folk music, American Patchwork, which aired on PBS in 1991. In his late seventies, Lomax completed a long-deferred memoir, The Land Where the Blues Began (1995), linking the birth of the blues to debt peonage, segregation, and forced labor in the American South.
