Physicists, astronomers, architects, geometricians, mathematicians, chronometer-makers, watchmakers: these are just some of the interested people who, through the years, have displayed a passion for the measurement of time. Their research led to major discoveries and inventions that are still relevant today. Whether physical or geometrical theories, natural laws or mechanical applications, their fundamental contributions have all made it possible to measure time with greater accuracy, to create timepieces to ever higher specifications while allowing aesthetic qualities to become more refined, and even to design increasingly efficient and modern production methods.
(1868 - 1945)
Famous Swiss chronometer-maker. A tireless researchworker, he studied the influence of atmospheric pressure and magnetic fields on the performance of chronometers, watch-oils and temperature-compensation. He invented the affix balance and published many works.
