Charles Édouard Guillaume was a renowned Swiss physicist who won the Nobel Prize in Physics in 1920 for his to precision measurements in Physics. His interest in taking up physics as a field of study began when he was a student, and later was motivated to pursue this as a career upon reading François Arago's text book, ‘Éloges académiques’. Throughout his career that spanned approximately five decades, he had been associated with the International Bureau of Weights and Measures, in various positions. His most notable works were his contributions in the field of metrology and alloys. His discovery of alloy ‘Invar’, that was impervious to thermal changes was regarded path-breaking in the field of science at that point. This was followed by his development of the alloy ‘Elinvar’. Charles Édouard Guillaume was also the first to determine the precise temperature of space. He also authored several books related to his field of study.
