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.
(1877 - 1957)
Professor of experimental physics at the University of Neuchâtel. He was interested in horological problems and published interesting articles on the influence of atmospheric pressure and magnetic fields on the rate of watches, glass balance-springs, the validity of Hooke's law, etc. Founder and president of the Swiss Chronometry Society and creator of the Swiss Laboratory of Horological Research, where physicists, chemists, metallurgists and horologists are trying to solve the problems of the construction of chronometric instruments.
