The collection contains materials related to Rosen’s work on Victory Without Violence: The First Ten Years of the St. Louis Committee of Racial Equality, a history of the St. Louis Committee of Racial Equality (CORE). The papers also include a small number of Yvonne “Bonnie” Rosen’s academic papers and her master’s thesis in the areas of social work and anthropology. The papers are divided into two series: the CORE Series dates from 1951 to 2001 and the Professional Series dates from 1955 to 1993. Both series are arranged alphabetically by title and/or topic with the bulk of the collection dating from 1994 to 1996. The CORE Series is comprised of materials relating to the book, Victory Without Violence. Members of the book’s editorial committee conducted oral history interviews and mailed a request for CORE reminiscences from former members. There is one corrected oral history interview transcript from Maggie Dagen’s interview and one note from Vivian Dreer concerning her CORE memoirs that she contributed for the book. There are excerpts from the interviews and memoirs that were likely used in the book. Rosen’s own memoir included not only her time in the St. Louis CORE, but also how she applied her CORE experiences to work in Philadelphia, Pennsylvania, and in West Lafayette, Indiana. She included history about her mother’s family in Minnesota, how she experienced racism for the first time on the Concordia Seminary grounds at the age of ten in 1938, and her experience during the Fairgrounds Park incident in 1949 (f.7). Four academic papers written by Bonnie Rosen and her membership card for the National Association of Social Workers comprise the Professional Series. The earliest paper is dated 1959 and is a data analysis conducted by Rosen for the Social Science Institute of Washington University entitled Attitudes of Nurses Toward Employment at Jewish Hospital. The latest paper is Rosen’s 1993 master’s thesis, A Family Study of the Patriarchs Abraham, Isaac, and Jacob.
