The Société Genevoise d’Instruments de Physique (SIP)

The company was founded in 1862 by Geneva scientists Auguste De la Rive (1801-1873) and Marc Thury (1822-1905) to manufacture scientific instruments. From 1870, under the impetus of Théodore Turrettini (1845-1916), it diversified its activities into new energy sectors (hydro-motors, refrigeration systems, electricity meters), as well as metrology (precision rules). This three-fold expertise led to the development, in 1921, of a machine tool that would contribute to the growth of mass production in mechanics, the pointing machine, called the “MP”, capable of machining with a precision of the order of a thousandth of a millimetre. A true technological feat, this production will make SIP one of the most prestigious machine manufacturers in the world. After employing up to 1 600 people (1969), a prisoner of its engineering culture, the company struggled to adapt to the economic changes that affected the industry from 1970 onwards. In 1990, SIP left its Plainpalais site for Satigny. In 2006, with only around 40 employees left, it was taken over by the StarragHeckert group.
