Paul Jarrico (1929-1996) was a Hollywood screenwriter working in the studio system in the 1930s and 1940s. A lifelong communist, he was subpoenaed before the House Committee on Un-American Activities in 1951. His refusal to comply with the Committee's questions saw him lose his job at RKO and placed on the so-called Hollywood "Blacklist." His films were marked by their marriage of art and politics, often commenting on the pressing issues of their time. Notably, his 1954 film Salt of the Earth, a collaboration between blacklisted filmmakers and the International Union of Mine, Mill and Smelter Workers, was regarded as a subversive critique of mid-century American capitalism.
Vladimir Rosing (1890-1963) was a Russian tenor, producer, and director (primarily of opera) who worked largely in Britain and the United States. His papers include ephemera relating to his vocal and directorial career, but principally comprises his writings on art and politics, as organized and edited by his wife, Ruth, and son, Richard.
