The Public Sectors comprising the City and the Canton of Bern are responsible for the operation of the Zentrum Paul Klee, together with the Regional Cultural Conference. As expenditure for the Centre’s operations depends on the investment costs, Public Sector representatives also sit on the Board of the Maurice E. and Martha Müller Foundation (MMMF).

The Public Sector’s role in the Zentrum Paul Klee is apparent from the agreement with the City, Canton and Civic Community of Bern signed on 3 July 1997.

This declaration of intent embodies the intentions of the parties to establish, equip and operate a museum dedicated to Paul Klee, subject to the following conditions (summary):

• Paul Klee’s heirs, Livia Klee-Meyer and Alexander Klee, are to make the works of Paul Klee and those of his artist friends and other works from that period currently in their possession available to the museum dedicated to Paul Klee.
• The Klee heirs are to contribute to the Klee archive.
• The Paul-Klee-Stiftung (Paul Klee Foundation – PKS) and the Art Museum are to make available the works of Paul Klee, the works of his artist friends and works from that period as well as works in other bequests and holdings, which are currently in their possession.
