The Paul Sacher Foundation was founded in 1973. At first, its purpose was to preserve Paul Sacher’s musical library. A short while later, the holdings began to be systematically expanded, and its purpose started to change. Today, the Foundation is an international research center for the music of the twentieth and twenty-first centuries, with some hundred estates and collections from leading composers and performers. <br><br>The main purpose of the Paul Sacher Foundation resides in the optimum care and study of its source materials. The Foundation also facilitates and supports scholarly research into its archival holdings by granting access to the documents available on its premises.
