The Walter Brenner Collection, housed in the Dr. Kenneth J. LaBudde Department of Special Collections, was donated in the early 1970s to the University of Missouri-Kansas City by Brenner’s spouse, Meta Rika Brenner. The collection is divided into three series: Manuscript Music Scores, Published Music Scores, and Miscellaneous Documents and Ephemera. Manuscript scores form the heart of the collection and date from 1930-1967, with the majority composed between 1941 and 1960. As Brenner was a copyist, many of the manuscript scores consist of different layouts of copy, drafts and versions of the same composition. This especially applies to the compositions which Brenner chose to revise later. These instances reveal Brenner’s compositional development and methodology. It may also be mentioned that Brenner chose certain pieces, such as God Is Love, to rework into different arrangements. For ease of researching works of this nature and all other works within this collection, an index has been provided. The published works, though few and on a smaller scale, prove his accessibility to public performance within a chamber or liturgical environment. Though there is little personal material within the series titled ephemera, his scrapbook and a small amount of correspondence will add to a researcher’s understanding of Brenner.
