Beverly Sills/Erich Krueger

Sachse corresponded with many prominent figures in the opera community in Europe and the United States throughout his life, and saved letters envelopes alphabetically arranged in a two-ring binder. Much of the correspondence relates to professional activities, and the largest part of the series consists of his significant correspondence with Richard Strauss. Correspondents with multiple items have individual folders, while folders 6 and 7 in Box 2 contain single items of correspondence, organized alphabetically by the last name of the correspondent. All correspondents are listed below. Sub-series C contains correspondence between Erich Kreuger and Beverly Sills regarding a 1945 letter from Strauss to Sachse along with a transcription in block letters and an English translation. Correspondence is largely in German, but examples of English, French, and Italian correspondence are also included. All items are in German unless stated otherwise below.
