After his death, the heirs of Hugo Kükelhaus donated the extensive estate which had been left in the artist’s former working rooms to the city of Soest. It contains the library, the literary, philosophical and artistic inheritance, the correspondence and also several personal documents and anthologies.
The estate stock was reviewed from 1988 to 1993 by a researcher in the Soest city archive. Due to its accessible sources, Soest is an important centre for the study of the life and works of Hugo Kükelhaus.
Since 1993 the Hugo Kükelhaus Society has been the responsible institution of the estate management. It took over the responsibilities agreed by contract from the city of Soest in close cooperation with the city archive and the heirs of Hugo Kükelhaus.
Literary and philosophical oeuvre: manuscripts of published and unpublished books and articles (ca. 100 unpublished manuscripts including several extensive book manuscripts) along with previous works, manuscripts of lectures, audio transmissions, poems etc.
Creative oeuvre: drawings, watercolors, prints; drafts of comic strips and work booklets; drafts and design sketches relating to the Erfahrungsfeld [field of sensory experience] as well as to the creative and interior architectural works, together with correspondence and the like
Collection of materials: as part of the exhibitions of the Erfahrungsfeld, seminars and miscellaneous projects by or in cooperation with Kükelhaus
Documents and materials: on his life and work, e.g. autobiographical records, diary, reviews and newspaper articles, photographs, sound and film documents
Correspondence: collection of letters from ca. 350 people and institutions, including extensive correspondence together with autographs of famous contemporaries (e.g. Eduard Spranger, Peter Suhrkamp, Ernst Meister, Hans Schwippert, Josef Pieper, Robert Jungk, Otto Bartning, Fritz Dietloff von der Schulenburg, Axel von dem Bussche, Ewald Mataré, Karlfried Graf Dürckheim, Martin Wagenschein, Hartmut von Hentig); and beyond that numerous individual letters;
Letters: by Kükelhaus himself (photocopies or carbon copies)
Collections: manuscripts and publications (without books) of friends and other people; creative works of others; photographs, compilation of newspapers and journal excerpts;
Partial bequest of his father and both his brothers, Heinz Kükelhaus and Hermann Kükelhaus, who were authors as well.
Supplemented bequest: primarily letters from Hugo Kükelhaus
Library: (ca. 3000 titles) and collection of journals
Furniture: supplement and maintenance of bequest
The so-called bequest supplement first of all applies to those letters sent by Kükelhaus that due to their significance are asked back from major correspondence partners. But it also applies to sketches that stayed with the executing workshop, creative works or original manuscripts he gave away as a present or the like.
So far numerous people and institutions have provided the Kükelhaus-Archive with letters and other partly extensive documents. Even furniture has already been placed at their disposal (e. g. from the company library of Schmöle in Menden that had been furnished by Kükelhaus).
The protection of Kükelhaus’ creations also includes assistance with preventing his creative works from destruction elsewhere. This is done by asking the owners for maintenance and preservation of the things in question (e. g. as has happened already in the case of the Church of the Redeemer in Essen, the Borromaeum Münster and the town hall of Vreden). These efforts to preserve the bequest have to be intensified still. Furthermore, a photographic documentation of the scattered creative works is needed.
