Charles Édouard Guillaume (February 15, 1861, Fleurier – May 13, 1938, Sèvres), was a French-Swiss Physicist who received the Nobel Prize in Physics in 1920 in recognition of the service he had rendered to precision measurements in physics by his discovery of anomalies in nickel steel alloys.
He is known for his discovery of nickel-steel alloys he named invar and elinvar. Invar has a near-zero coefficient of thermal expansion, making it useful in constructing precision instruments whose dimensions need to remain constant in spite of varying temperature. Elinvar has a near-zero thermal coefficient of the modulus of elasticity, making it useful in constructing instruments with springs that need to be unaffected by varying temperature, such as the marine chronometer. Elinvar is also non-magnetic, which is a secondary useful property for antimagnetic watches.
Guillaume worked with Kristian Birkeland. He served at the Observatoire de Paris—Section de Meudon. He conducted several experiments with thermostatic measurements at the observatory. He was the first to determine the correct temperature of space.
He married A.M. Taufflieb in 1888, and together had three children.
