The Charles Reiner Collection consists of correspondence, newspaper reviews and clippings, performance programmes, personal documents including legal material, photographs, writings, published and unpublished music by Reiner and other composers, audio and visual recordings of Reiner and other performers, books, and awards. Of particular interest is correspondence from Rudolf Serkin, Alfred Cortot, and Kurt Waldheim; legal documents from both before and after Reiner’s immigration to Canada; and the extensive collection of programmes and newspaper clippings that document Reiner’s extensive performance career.
