Catalogue Raisonné

One of the main goals of Fondation Constant is to realise a website offering access to the full body of work created by Constant during his lifetime, a so called digital catalogue raisonné. To set up the database for this, Fondation Constant is in the process of gathering all data regarding Constant’s works of art and their whereabouts. There are several ways in which you can help the foundation to realise this goal.

If you are in possession of works of art by Constant Nieuwenhuys and want us to examine it for inclusion in the database, you can do so by downloading, filling in and returning a questionnaire about the work(s) they possess.

When you posses one or two pieces and want to provide a detailed description of the work, please fill in the form below:
Choose the option oral assessment at the start of the form and add CR in the last comment box.
Pleas note that general terms and conditions apply!

When the work of art is known to the foundation and no doubt exists about it’s authenticity, the foundation will ask the owner to allow our professional art photographer to take high-resolution photographs* of the work. The work of art will then be added to the catalogue raisonné.

The writing of the catalogue raisonné is suported by the Academic Committee, which advises the board on best practices, content, quality measures and procedures and format.

The Academic Committee consists of:
Dr. Dolf Broekhuizen: Architecture Historian
Chair and member of the board of Fondation Constant
Dr. Els Hoek: Author of the catalogue raisonné of Theo van Doesburg and curator at Museum Boijmans van Beuningen
Prof. dr. Katja Kwastek: Professor of Art History of the Modern Age bij de Faculteit der Letteren van de VU Amsterdam
