sixty physical, optical, anatomical and medical instruments to professor Johann Daniel Doistenius
at Marburg University, Gemiany, Dorstenius bought these on his own initiative and out of his own
pocket. With his lectures he intrcxJuced experimental physics to Marburg.

letters, invoices, instructions for use and the earliest instrument-makers' trade catalogue. These
dcxruments contain unique information on the repertoire and the business organization of the
Musschenbroek workshop with its close connections with the progressive University of Ixiden.
