University of Paris alumni

Evry Léon Schatzman (16 September 1920 – 25 April 2010) was a French scientist hailed as "the father of modern French astrophysics".

Louis Jean-Baptiste Alphonse Bachelier (French: [baʃəlje]; 11 March 1870 – 28 April 1946) was a French mathematician at the turn of the 20th century. He is credited with being the first person to model the stochastic process now called Brownian motion, as part of his doctoral thesis The Theory of Speculation (Théorie de la spéculation, defended in 1900).
Bachelier's doctoral thesis, which introduced the first mathematical model of Brownian motion and its use for valuing stock options, was the first paper to use advanced mathematics in the study of finance. His Bachelier model has been influential in the development of other widely used models, including the Black-Scholes model.
Bachelier is considered as the forefather of mathematical finance and a pioneer in the study of stochastic processes.

Jean-Antoine Auguste Metz (8 August 1812 – 22 June 1854) was a Luxembourgian entrepreneur, politician, and lawyer. He was a major player in the growing steel industry in Luxembourg during the nineteenth century, as well as a leading liberal member of the Chamber of Deputies, along with his brothers.
Born in Luxembourg City as the youngest of nine children of Jean Metz, Auguste Metz attended the Athénée de Luxembourg, before leaving to study law at the University of Paris in 1833. He gained his licence to practice law in France, but returned to Luxembourg, where he became involved in the steel industry. In 1837, Metz and his brothers Charles and Norbert, were given a ten-year lease of the steel mill at Berbourg. They formed a company, Auguste Metz & Cie, along with Théodore Pescatore, for the purpose of expanding and redeveloping the site. The company expanded, taking over foundries at Grundhof, in the Red Lands, at Eich, and at Fischbach.He first became involved in politics through his opposition to the Third Partition of Luxembourg in 1839. In 1848, Metz sat on Luxembourg's Constituent Assembly, and then the first Chamber of Deputies, elected in 1848 to represent Grevenmacher. He was targeted in the 1854 election by the Simons government. He would not live to see the assembly of the new Chamber of Deputies, however, as he died in Eich just eight days after the election, having fallen ill inspecting the foundry at Berbourg, exacerbated by tonsillitis.He married Petronille Laeis on 17 August 1841. They had four children, including Léon Metz, who became a member of the Chamber of Deputies for forty-three years and Mayor of Esch-sur-Alzette for three years.

Bernard d'Espagnat (22 August 1921 – 1 August 2015) was a French theoretical physicist, philosopher of science, and author, best known for his work on the nature of reality. Wigner-d'Espagnat inequality is partially named after him.
Quote: "The doctrine that the world is made up of objects whose existence is independent of human consciousness turns out to be in conflict with quantum mechanics and with facts established by experiment."

Auguste Henri André Duméril (30 November 1812 – 12 November 1870) was a French zoologist. His father, André Marie Constant Duméril (1774–1860), was also a zoologist. In 1869 he was elected as a member of the Académie des sciences.
Duméril studied at the University of Paris, and in 1844 became an associate professor of comparative physiology at the university. From 1857, he was a professor of herpetology and ichthyology at the Muséum National d'Histoire Naturelle in Paris.
In 1851, with his father, he published Catalogue méthodique de la collection des Reptiles. With zoologist Marie Firmin Bocourt (1819–1904), he collaborated on a project called Mission scientifique au Mexique et dans l'Amérique Centrale, a publication that was the result of Bocourt's scientific expedition to Mexico and Central America from 1864 to 1866. The section on reptiles is considered to be Dumeril's best written effort in the field of herpetology. Duméril died in 1870 during the siege of Paris, and Mission scientifique au Mexique et dans l'Amérique Centrale was continued by Bocourt, Léon Vaillant (1834–1914) and other scientists.
As part of the Collection des Suites à Buffon, he issued a two-volume ichthyological study titled Histoire naturelle des poissons, ou Ichtyologie générale (1865, 1870), research that complemented the works of Georges Cuvier (1769–1832) and Achille Valenciennes (1794–1865) by describing species not covered by the two famous naturalists. Duméril also conducted significant research involving the axolotl (Ambystoma mexicanum).

Robert Degos (1904–1987) was a French dermatologist who described several dermatoses including Degos disease which he first described in a seminal paper published in 1942 in the French journal of dermatology and syphilology.

Louis Édouard Octave Crouzon (1874–1938) was a French neurologist born in Paris.
He received his doctorate from the University of Paris, where he studied under Paul Georges Dieulafoy (1839–1911), Joseph Babinski (1857–1932) and Pierre Marie (1853–1940). During his medical career, he was associated with the Hôtel-Dieu de Paris and Salpêtrière Hospital.Crouzon specialized in hereditary neurological diseases, especially spinocerebellar ataxia. He did extensive work associated with cervical and lumbar spine deformities, and conducted studies of chronic rheumatic and arthritic disorders. Crouzon was the first to describe a condition he called "craniofacial dysostosis", defined as a genetic branchial arch disorder that results in abnormal facial features. Today this condition is known as Crouzon's syndrome.For his entire career, Crouzon was interested in psychology, particularly in the work of Pierre Janet (1859-1947), whom Crouzon considered a major influence.During his career, he was president of the Société Neurologique de Paris (Neurological Society of Paris) and secretary of the journal Revue Neurologique.

Étienne Jacques Marie Raymond Céstan (6 April 1872, Gaillac – 1934) was a French neurologist.
From 1892 he studied medicine in Paris, and was subsequently a hospital interne and a student of Édouard Brissaud at the Salpêtrière. In 1899 he received his medical doctorate, and was chosen by Fulgence Raymond to be chef de clinique at the Salpêtrière. In 1903 he was put in charge of the histopathology laboratory, and during the following year, he obtained his agrégation. Soon afterwards, he moved to Toulouse, where in 1913 he attained the chair of psychiatry. At this position he conducted research on the development of cerebrospinal fluid and the effects of intra-ventricular injection.

Joseph Valentin Boussinesq (pronounced [ʒɔzɛf valɑ̃tɛ̃ businɛsk]; 13 March 1842 – 19 February 1929) was a French mathematician and physicist who made significant contributions to the theory of hydrodynamics, vibration, light, and heat.

Adam Asnyk (11 September 1838 – 2 August 1897), was a Polish poet and dramatist of the Positivist era.
