In one of its most famous projects, Federal Project Number One, the WPA employed musicians, artists, writers, actors and directors in arts, drama, media, and literacy projects. The five projects dedicated to these were: the Federal Writers’ Project (FWP), the Historical Records Survey (HRS), the Federal Theatre Project (FTP), the Federal Music Project (FMP), and the Federal Art Project (FAP). In the Historical Records Survey, for instance, many former slaves in the South were interviewed; these documents are of great importance for American history. Theater and music groups toured throughout the United States, and gave more than 225,000 performances. Archaeological investigations under the WPA were influential in the rediscovery of pre-Columbian Native American cultures, and the development of professional archaeology in the US.
