Biographie
-
Jean Wagner arrived in Paris in 1812 where he was brought up by his uncle J.B. H. Wagner (qv ) and was trained as a clock-maker by him and by his cousin Bernard Henri with whom he worked until he established his own business c. 1830. Apart from wide-spread, and inventive, activity in horology, he made metronomes for Maezel and collaborated with Morin in the development of his form of Atwood machine. Among other instruments with which he was involved are a simplified form of Watt's dynameter, engine-counters and celerimeters. At the 1839 exhibition he showed a recording dynamometer for the effort exerted on a revolving arbor (1). In 1849 he made the marégraphe of Chazallon, a self-registering tide-meter which became widely used in France and elsewhere. An hodometer carrying his name is also known (2).
