Advisory Board

In mid-2004, VAN HAM became the first German art auction house to establish an advisory board. For this body, Markus Eisenbeis was able to recruit renowned personalities from the fields of science, business, and journalism, who advise the management in setting and pursuing strategic goals on the German and international art markets.

Prof. Dr. Albert Mayer is an trained economist and designated art collector. He was in the course of his career managing director of the German Magazine Publishers Association and the Rheinische Post in Dusseldorf. In May 2004 he was awarded by the Prime Minister Peer Steinbrück with the Order of Merit of the country for the services to the media location North Rhine-Westphalia.

Since August 2018, the renowned art historian Drs. Guido de Werd has been a member of the advisory board of VAN HAM. The former director of the Museum Kurhaus Kleve is thus replacing the founding member Wilhelm Karl Prinz von Preußen, who has accompanied the rapid development of the Cologne auction house since 2004 as chairman of the advisory board and is now retiring for reasons of age. De Werd has published numerous publications on late medieval art, Dutch Romantic art and modern art, including the work of Ewald Mataré, and the present. His authoritative museum work and numerous publications have earned Guido de Werd important awards such as the Order of Knights of Orange-Nassau and the Federal Cross of Merit, First Class. 

We are very pleased to welcome Rene Spiegelberger as a new member of the VAN HAM Advisory Board since 2022. As a proven art connoisseur, he founded the Spiegelberger Art Foundation for the promotion of artists, art education and the development of collections. In addition to his honorary commitments in associations and foundation boards of trustees as well as mandates in advisory boards and supervisory boards, Spiegelberger is a member of the federal board of the Wirtschaftsrat. He regularly lectures on the art market and is the author of numerous specialist articles. Spiegelberger is part of the board of trustees of the Beuys Museum Schloss Moyland and initiated the publication series 'International Artists Look at Switzerland' with the Neue Zürcher Zeitung (NZZ).

It is with great sadness that we bid farewell to our long-time advisory board member and "ambassador" of the house, Prof. Ottmar Braun. Since VAN HAM was the first German art auction house to establish an advisory board in mid-2004, he supported the management with heart and soul in setting and pursuing strategic goals.
