Christian Tümpel was until 2002 Professor of the History of Art in Nijmegen/ The Netherlands. He has devoted his life to researching Rembrandt, starting in 1968 with his doctoral dissertation about Rembrandt’s historical paintings, which earned him a fellowship with his wife Astrid T?mpel at the Warburg Institute in London the following year. In 1971 he was awarded the Prize of the Dutch Royal Academy of Science for his studies of Rembrandt, an honour the academy only bestows every twenty years. He has contributed to the catalogues of numerous international exhibitions, most recently to the anniversary exhibition Rembrandt – Zoektocht van een genie at the Rembrandt House in Amsterdam; and has presented papers at conferences in Washington, Sacramento, Detroit, Amsterdam, Antwerp, Berlin and Hamburg. He was involved in the curatorial preparation of major exhibitions of Dutch art and 19th century sculpture in Amsterdam, Haarlem, Nijmegen, Jerusalem and Berlin. His essays and books on Dutch art and on Rembrandt have been translated into many languages.
