Marie Paul Auguste Charles Fabry, born in Marseille on June 11, 1867 and died in Paris on December 11, 1945, is a physicist ( A physicist is a scientist who studies the field of physics, that is to say…) French.

Biography

Charles Fabry is the brother of the mathematician (A mathematician is in the restricted sense a researcher in mathematics, by any extension…) Eugène Fabry, of the astronomer (An astronomer is a scientist specialized in the study of astronomy.) Louis Fabry and magistrate Auguste Fabry. His mother, Marie Estrangin, was a first cousin of Edmond Rostand. He entered ranked 17th at the École Polytechnique in 1885 and left 23rd and resigned in 1887. He then prepared for the physics aggregation exam where he was accepted in 1889. He therefore devoted himself to everything (All inclusive as a whole of this which exists is often interpreted as the world or…) firstly to the teaching of physics at the high school, in Pau (1889), Nevers (1890), Bordeaux (1892), Marseille (1893), then at the Saint-Louis high school (The Saint-Louis high school is a higher education establishment located at 44…) in Paris (1893), while simultaneously preparing for the doctorate in science under the direction of Jules Macé de Lepinay, professor of physics at the Faculty of Sciences of Marseille. In 1892, he defended his thesis at the Faculty of Sciences of Paris on the Theory of visibility (In meteorology, visibility is the distance at which it is possible to…) and the orientation (In the literal sense, the orientation designates or materializes the direction of the Orient (sunrise…) of the interference fringes.

In 1894, he obtained a position as lecturer for the PCN certificate at the Faculty of Sciences of the University of Marseille. He joined the laboratory of Jules Macé de Lepinay. He succeeded Alfred Perot (Jean Baptiste Gaspard Gustave Alfred Perot is a French scientist, born in Metz on November 3…), in 1904, as professor at the chair of industrial physics. Pierre Sève (In botany and plant physiology, sap is the liquid medium that circulates…) will replace him when he leaves for Paris.

Collaborating with Henri Buisson, having succeeded him as lecturer, and Alfred Perot, he participated in the development (Graphics) of the Fabry-Perot interferometer, which he used in particular to demonstrate, in 1913, the reality of the existence of the ozone layer (Ozone (or trioxygen) is a chemical compound containing 3 atoms…), until now only suspected, and determines its proportion according to the atmospheric layers. Jean Cabannes works in his laboratory to prepare his doctoral thesis. It also demonstrates, through experience, the Doppler-Fizeau effect (The Doppler effect is the frequency shift of an acoustic wave or…), applied to the field of optics.

In 1921, he returned to Paris as holder of the chair of physics at the Faculty of Sciences of Paris previously occupied by Edmond Bouty and director of the physics teaching laboratory, with collaborators Eugène Darmois and Louis Décombe, then François Bedeau. He also became the first general director of SupOptique (Institute of theoretical and applied optics).

In 1927 he was appointed professor at the École Polytechnique, following the death of Alfred Perot, and elected to the Academy of Sciences (An academy of sciences is a learned society whose role is to promote research…), succeeding Daniel Berthelot (Charles Fabry 51 votes, Paul Langevin (Paul Langevin, born in Paris on January 23, 1872 and died in…) 1 vote, Henri Abraham (Henri Abraham (1868-1943) French physicist.) 1 vote, Georges Sagnac 1 vote).

His work as a physicist is almost exclusively devoted to optics, in particular to interferometry, spectroscopy and photometry.

In 1937, he founded with Henri Chrétien (Henri Chrétien (1879 – 1956) is an astronomer, engineer-optician, professor and inventor…), Georges Guadet and André Bayle the Society for Research and Studies in Optics and Related Sciences and must leave his chair at the Faculty of Sciences of Paris and the École Polytechnique, where he is replaced by Louis Leprince-Ringuet (Louis Leprince-Ringuet, born March 27, 1901 in Alès and deceased…).

He was honorary president of the French Photography Society from 1935 to 1937, succeeding Georges Perrier, and president of the French Physical Society in 1924. He was made a foreign member of the Royal Society in 1931.
