The purpose of the foundation is to support the descendants of Heinrich Zschokke (1771-1848) in Aarau and their spouses, if necessary, to cover the costs of education, equipment or in cases of need or for similar purposes. In addition to non-repayable contributions, loans can also be granted. The beneficiaries do not have a legal claim to the foundation. Contributions can also be made to serve the family's cohesion. The foundation's services are at the discretion of the foundation board, which makes the final decision.
