Resumen de Instruments, Tools and Materials: The Inventories of the Workshops of Two Important Instrument Makers: Jules Duboscq and Heinrich Ruhmkorff
The Minutier central des notaires de Paris, which is preserved in the Archives nationales in Paris, is a huge archive group with several millions of documents recording all the official deeds written by the Parisian notaries. In it, it is possible to find very interesting documents concerning the activities of 19th century Parisian scientific instrument makers. I publish here the inventories of the instruments and tools which were in the workshop of two important makers: Jules Duboscq (1817–1886) and Heinrich Daniel Ruhmkorff (1803–1877). The first was compiled in 1859 after the death of Duboscq’s wife, the second when Ruhmkorff workshop was sold in 1878. These documents contain precious and original information concerning the organisation of the workshop, the instruments, the activities, and the trade of these renown instrument makers.
