Objective of the workshop:

    The BIPM is hosting a symposium to celebrate the life and work of Charles-Édouard Guillaume, Director of the BIPM from 1915-1936. The year 2020 marks the centenary of his award of the Nobel Prize in Physics "in recognition of the service he has rendered to precision measurements in physics by his discovery of anomalies in nickel steel alloys".

    Guillaume dedicated more than half a century to metrology. His major study of the properties of nickel-iron alloys spanned more than twenty-five years and not only revolutionized geodesy measurements but also chronometry and precision horology. Numerous applications still exist for these alloys.
