Biography

His/her mother was the German cousin of the mother of Edmond Rostand. It enters classified 17th to the Polytechnic school in 1885 and fate 23e and resigner in 1887. It prepares then the contest of aggregation of physics where it is received in 1889. It is devoted to a career of teacher, obtaining in particular a post of professor with Pau (1889), Nevers (1890), Bordeaux (1892), Marseilles (1893), then with the Lycée Saint-Louis in Paris (1893), while simultaneously preparing the science doctorate under the direction of Jules Macé de Lepinay, professor with the Faculty of Science of Marseilles. In 1892, it supports with the Faculty of Science of Paris its thesis on the Théorie of the visibility and the orientation of the interference rings .

In 1894, he is recalled to Marseilles, where one entrusts to him, with the Faculty of Science, a station of university lecturer, succeeding Alfred Perot. He joined the laboratory of Jules Macé de Lepinay. He succeeds to him his death, in 1904, as a professor with the pulpit of industrial physics. Pierre Sève will replace it with its departure for Paris.

Collaborating with Henri Bush, him having succeeded as university lecturer, and Alfred Perot, it takes part in the development of the Interféromètre of Fabry-Perot, which is in particular used to him to show, in 1913, the reality of the existence of the Couche of ozone, up to that point only suspected, and the proportion according to the atmospheric layers determines some. Jean Cabannes works in his laboratory to prepare its thesis of doctorate. It also shows, by the experiment, the Effect Doppler, applied to the field of optics.

In 1921, it returns to Paris like holder of the pulpit of physics of the Faculty of Science of Paris previously occupied by Edmond Bouty and becomes the first managing director of SupOptique (Institute of optics theoretical and applied).

In 1927 it is named professor with the Polytechnic school, following the death of Alfred Perot and is elected with the Academy of Science, succeeding Daniel Berthelot (Charles Fabry 51 votes, Paul Langevin 1 vote, Henri Abraham 1 vote, Georges Sagnac 1 vote).

Its work of physicist is almost exclusively devoted to the Optique, in particular to the Interférométrie, the Spectroscopie and the Photométrie.

In 1937, it founds with Henri Chrétien, Georges Guadet and André Bayle the Company of research and studies in optics and sciences related and must leave its pulpit of the Faculty of Science of Paris and Polytechnic school, where it is replaced by Louis Leprince-Ringuet.

He is honorary president of the French company of photography of 1935 to 1937, succeeding Georges Perrier, and chair French company of physics in 1924.
