Professional experience

After training as a paintings conservator at the Österreichische Galerie in Vienna and the Herzog Anton Ulrich-Museum in Braunschweig (1979 - 1980) I concentrated on glass conservation, working for three years at the Restaurierungszentrum, Düsseldorf (1981 - 1983), followed by voluntary work conserving glass vessels at the Römisch-Germanisches Museum in Cologne and the Museum für Kunst und Gewerbe in Hamburg (1983/ 1984). My knowledge and experience of conservation and restoration of paint on canvas and on glass constituted a solid basis for treating reverse paintings on glass (Hinterglasmalerei). I acquired technical skills in this field in 1984 at the workshop of the Bayerisches Nationalmuseum in Munich, and in 1985 became a self employed conservator specializing in the conservation/ restoration of reverse paintings on glass.

I have restored reverse painted glass obejcts for major museums and private collections in Germany and other countries including the U.S.A., Great Britain and Switzerland. After years of conservation in the field of folk art - reverse painted glass of the 19th century, I was experienced enough for highly demanding restoration work. These included first quality objects from the 14th through the 18th century, which were presented in the following exhibitions on reverse paintings on glass.

The conservation/ restoration of highly valuable reverse painted tankards, double-walled bowls and reverse-glass paintings by Hans Jakob Sprüngli (about 1559 - 1637), Zurich represent the most demanding projects of my professional career to date. These objects of treasure-chamber quality are exhibited at the Schweizerisches Landesmuseum in Zurich, the Hessisches Landesmuseum in Kassel, the Staatliches Museum in Schwerin (conservation financed by the Rudolf August Oetker Stiftung für Kunst, Kultur, Wissenschaft und Denkmalpflege, Bielefeld) and at the Schloßmuseum, Stiftung Schloß Friedenstein in Gotha (conservation financed by the Ernst von Siemens Kunststiftung, Munich).

My work also includes the treatment of reverse-glass paintings integrated in medieval altars, in cabinets and mirrors. The conservation/ restoration of seven reverse painted glass inlays of a house altar, South Germany, probably Nuremberg, about 1560 - 1580 of the Corning Museum of Glass, Corning (USA) was accomplished in 2007. The project was financed by the Getty Foundation, Los Angeles (USA) and technically supported by the Doerner Institut.

My activities also include research projects (→ main menu "Research Projects"), book publications (→ main menu "Book Publications") delivering lectures in Germany and abroad, for example for the “Conferences on reverse paintings on glass” (→ main menu "Conferences") and the training of colleagues and students in the conservation of reverse paintings on glass. I have taught courses comprised of lectures and practical demonstrations at the Victoria & Albert Museum in London, West Dean College in Chichester (GB) and the Netherlands Institute for Cultural Heritage in Amsterdam (NL).
