Georges Frederic Roskopf (15 March 1813 – 14 April 1889), the inventor of the pin-pallet escapement, was born in Germany and became a naturalized Swiss citizen.
Early life and introduction
In 1829, when Roskopf was 16, he went to La Chaux-de-Fonds and began training in commerce with F. Mairet & Sandoz, who dealt in ironmongery and watch parts. In 1833 he decided to become a watchmaker and went as an apprentice to J. Biber, in La Chaux-de-Fonds, to learn watchmaking.
Career as a watch maker and specialist
Financed by his wife, he then set up in business as an établisseur, that is, a watch producer who bought the ebauche and all other parts of the watch and assembled them. He made cylinder and lever watches for export to North America and Belgium. Although the watches were well made, the business was not profitable and in 1850 Roskopf sold it. In 1851 Roskopf became the joint manager of the La Chaux-de-Fonds branch of B. J. Guttman Frères of Wurzburg. They manufactured English-type watches. In 1855 he set up in business with his son, Fritz Edouard, and Henri Gindraux as "ROSKOPF, GINDRAUX & CO." After two years his son opened his own business in Geneva and Gindraux went to Neuchatel to become the Director of the Watchmaking School.
Roskopf was an idealist who dreamed of making a good quality, cheap watch for working men. To accomplish this he used an old idea and reworked it, that of having the hands driven directly by the mainspring. In 1860 he began to design such a watch, which could be sold for 20 francs, and would still be of excellent quality, simple and solid. The watch had a large barrel in the center. a "Perron" pin-pallet escapement, and a monometallic balance. After discussions with Moritz J. Grossman he adopted the simple detached pin lever escapement. |
