Biography

After its studies with the National university, it supports its thesis in 1876, “On the property of the cubic lefts and the helicoid movement of a solid body”. Then it is devoted to teaching and becomes university lecturer of mathematics at the Teacher training school. It is named in 1885 professor of Mechanic with the Faculty of Science of Paris, from which he is the senior of 1903 with 1920, and in 1895 professor with the central Ecole of arts and manufactures. He is elected member of the Academy of Science in 1892. He is vice-chancellor of the Academy of Paris, of 1920 with 1925, and extraordinary professor at the university of Rome and professor with the Université Harvard, where he with the chance to teach with Marston Morse, with which he shares same passion and becomes friendly.

He first of all worked in projective Géométrie in the line of Chasles, then on the algebraic functions, the differential equations and the Analyze complexes.

Paul Appell was Dreyfusard and counted among the first signatories of the Manifeste of the intellectuals ; its early engagement involved that of part of the scientific community; it intervened as expert with the revision of the lawsuit in 1906. On an idea of Albert Kahn, it created in 1914 the national Help, of which the vocation is “to come to assistance of the women, the children, with the old men, without reference of opinions and religious beliefs”, and becomes the first president about it.

Paul Appel was in addition president of the mathematical Société of France in 1885 and 1923 and chair French association for the Société of the Nations. He also created the funds of assistance to the scientific research which opened the way with CNRS. He was Grand-Croix of the Légion of honor. He founded in 1920 the Cité international academic of Paris, inaugurated in 1925, and chaired in 1921 the French conference for the scientific property.

His wife was the girl of Alexandre Bertrand (archeologist), cousin of Emile Picard, niece of Joseph Bertrand and Charles Hermite. His/her daughter Marguerite Appell married the mathematician Emile Borel and was a woman of letters known under the pseudonym of Camille Marbo. His/her son Pierre Appell was in particular appointed and under-secretary of State to Public works.

Within the Foundation of France, the Foundation Ars Cuttoli - Paul Appell supports the scientific research.
