Dietmar Stock-Nieden spent 21 years as a senior art expert with a Zurich-based art insurer after initially working for various auction houses in Bern and Zurich as an art appraiser and specialist. He studied art history, prehistory & early history, and classical archaeology at the Justus Liebig University in Giessen and the Albert Ludwig University in Freiburg im Breisgau. He received his doctorate for a dissertation on buildings by Vitra Design GmbH in Weil am Rhein.
The Institute’s services in the field of Expertise and Appraisals include authentications of Swiss art, valuations of single works and entire collections, independent damage assessments and general consultancy around the sale and purchase of art works.
Barbara Nägeli led the department with great success for 21 years and stepped down from her responsible role in mid-April 2021 upon obtaining her pension. We are delighted that in Dietmar Stock-Nieden we have found an experienced, competent successor to head Expertise and Appraisals at SIK-ISEA.
