Abstract The theater collection (1882-1991) consists of the papers of several men and women who were prominent in Utah theater during the twentieth century. Nearly all were peers; many working together periodically, either under the direction of Maud May Babcock or as members of the Moroni Olson Players during the 1920s. Each collection of papers has been treated as a separate collection. These collections contain thesis, biographies, programs, news clippings, correspondence, and other related materials.
