Scientific Instruments: Originals and Imitations. The Mensing Connection

15 - 16 October 1999
Museum Boerhaave Leiden, The Netherlands

This symposium is part of the Anton Mensing Scientific Instrument Project, a joint venture of the Museum Boerhaave, Leiden, the Nederlands Scheepvaartmuseum, Amsterdam, the Utrecht University Museum and the Adler Planetarium and Astronomy Museum, Chicago. It aims to trace, catalogue and research the instruments owned by Anton W.M. Mensing (1866-1936), director and owner of Frederik Muller & Co., auctioneers in Amsterdam. Ever since they were dispersed, there have been doubts on the authenticity of a section of the Mensing instruments; indeed, several have been proved to be forgeries. The symposium will address the problem of authenticity and historic scientific instruments.

The registration fee is 200 Nederlandsche Gulden (approximately $95), and includes lunches and drinks as well as a copy of the proceedings, which will be edited by Peter de Clercq and published in the series of Museum Boerhaave Communications.
