Charles-Victor Mauguin (French: [ʃaʁl.vik.tɔʁ mo.gɛ̃]; 19 September 1878 – 25 April 1958), more often Charles Mauguin, was a French mineralogist and crystallographer. He and Carl Hermann invented an international standard notation for crystallographic groups called Hermann–Mauguin notation (also sometimes called international notation).
François Joseph Herrgott (12 September 1814, Guebwiller – 4 March 1907, Nancy) was a French surgeon and obstetrician.
In 1839 he graduated from the University of Strasbourg, where he was a student of Louis Jacques Bégin (1793–1859) and Joseph-Alexis Stoltz (1803–1896). In 1841 he relocated to Belfort, where in 1849 he was appointed chief surgeon at the Hôpital de Belfort. In 1854 he obtained his agrégation at Strasbourg, later becoming chief physician of the Hôpital Civil in Strasbourg.
From 1872 he was associated with the Faculté de médecine at Nancy, where in 1879 he succeeded his former mentor, Joseph-Alexis Stoltz, as chair at the clinic of obstetrics. A few years later he was appointed director of the Maternité et de l'École départementale des sages-femmes.
Jean Alexandre Eugène Dieudonné (French: [ʒɑ̃ alɛksɑ̃dʁ øʒɛn djødɔne]; 1 July 1906 – 29 November 1992) was a French mathematician, notable for research in abstract algebra, algebraic geometry, and functional analysis, for close involvement with the Nicolas Bourbaki pseudonymous group and the Éléments de géométrie algébrique project of Alexander Grothendieck, and as a historian of mathematics, particularly in the fields of functional analysis and algebraic topology. His work on the classical groups (the book La Géométrie des groupes classiques was published in 1955), and on formal groups, introducing what now are called Dieudonné modules, had a major effect on those fields.
He was born and brought up in Lille, with a formative stay in England where he was introduced to algebra. In 1924 he was admitted to the École Normale Supérieure, where André Weil was a classmate. He began working in complex analysis. In 1934 he was one of the group of normaliens convened by Weil, which would become 'Bourbaki'.
Ferdinand Monoyer (9 May 1836 – 11 July 1912) was a French ophthalmologist, known for introducing the dioptre in 1872.
He invented the Monoyer chart, used to test visual acuity. He inserted his name in the random letters of the chart. It appears when one reads vertically from bottom to top on each side.
François Gény (1861–1959) was a French jurist and professor of law at the University of Nancy, who introduced the notion of "free scientific research" to the interpretation of positive law.
His advocacy of judicial discretion in the interpretation of statutory law had an important influence across Europe. Gény also emphasized that judges should take into account social and economic factors when deciding cases.
