Paul Ditisheim
Chronometrist who won many observatory prizes and studied the effects of temperature and pressure on timekeeping.
Paul Ditisheim (1868–1945) founded his own firm in La Chaux-de-Fonds in 1892 and specialised in precision pocket and marine chronometers that won numerous observatory trials. He researched balance materials and the influence of atmospheric pressure, worked with Charles-Édouard Guillaume on new alloys, and also produced the Solvil brand.
