The Sturzenegger Foundation was founded on 26 February 1987 by the couple Dr Hans and Claire Sturzenegger-Jeanfavre. Its collection is made available on permanent loan to the Museum zu Allerheiligen and Schaffhausen City Library. The acquired items are selected for their artistic or historical quality.

Besides acquisition, the Foundation also ensures the maintenance (restoration, care, indexing) and presentation of the items. It works closely with the museum and the city library, supporting their work by facilitating exhibitions, projects, scientific articles and other publications.

To fulfil this task, the board of trustees is in constant, open dialogue with the city council, the management of the museum and its curators, the associations close to the museum and the management of the city library. In this context it advocates for sensible, future-oriented and consensual solutions.
