====== Heuer, Edouard ====== {{wst>image_r|Heuer,_Edouard|Edouard Heuer (1840-1892)}} **Edouard Heuer** was a Swiss watchmaker and founder of the watch company [[Heuer]]. He was was born [[1840]] as son of a shoemaker in Brügg, Canton of Bern. [[1860]], he founded the watch [[manufacture]] [[Heuer]] in [[Saint-Imier]] in the Swiss Jura. [[1864]], he moved with the company to [[Biel]]. Already [[1876]], he founded a branch in London. Edouard Heuer ventured as the first watchmaker to the series production of [[chronograph]]s. His approach was to manufacture [[chronograph]]s technically easier and therefore cheaper, so he turned his attention primarily to the simplification of the usual clutch for the chronograph mechanism. This consisted of several components, and their production, finishing and assembly constitute a significant cost factor. He developed the so called [[oscillating pinion]], which is an effective module a movable [[shaft]] mounted with two sprockets. The one pinion is in constant engagement with the [[second wheel]] of the [[watch movement]], while the opposite after pressing the start [[pusher]] after a short swing grips into the [[chronograph]] center wheel. By this the connection is established, and the [[chronograph]] is running. By pressing another button the oscillating pinion is again moved away from the center wheel, and the [[Chronograph]] stops. For this development, the authority of the Paris 'Bureau for Industrial Property' issued a patent on May 3, [[1887]]. This principle finds application to the present day, for example, in the known and most widely used [[self-winding]] [[chronograph]] movement [[Valjoux 7750]]. From [[1880]] Edouard Heuer as first watch maker introduced the series production of [[chronograph]]s. Edouard Heuer died on April 30, [[1892]]. On January 1, [[1964]] the watch [[manufacture]] [[Heuer]] and the [[Leonidas|Leonidas Watch Factory]], [[Saint-Imier]] merged to [[Heuer-Leonidas]]. In [[1985]], the merger was done with the Techniques d'Avant Garde TAG Group and so the name was changed to [[TAG Heuer]], which is one of the best known watch brands of today. ===== Literature ===== *[[TAG Heuer - Die Beherrschung der Zeit]]; Author [[Gisbert L.
