Jeanne Radegonde Marie Charpentier (30 October 1903 – 9 October 1994){{r|yks|escofier}}{{cite web |title=CHARPENTIER Jeanne Radegonde Marie |url=https://deces.matchid.io/id/EeW8Iu0DbDLe |website=Match ID Fichier des décès |access-date=20 May 2023}} was a French mathematician. She was the first woman to obtain a doctorate in pure mathematics in France,{{r|yks}} and the second woman, after Marie-Louise Dubreil-Jacotin, to obtain a faculty position in mathematics at a university in France.{{r|lfmr}}
Charpentier was born in Poitiers, the daughter of Michel Marie Eugène Charpentier and Marie Thérèse Geneviève Rondelet, on either 29[https://www.data.gouv.fr/fr/datasets/fichier-des-personnes-decedees/ France, Death Records, 1970–2018] or 30 October 1903.Vienne, France, Births, Marriages, and Deaths 1540–1906
Education
Charpentier joined the Société mathématique de France in 1930, possibly their second female member after Édmée Chandon.{{r|yks}}
She was a student of Georges Bouligand at the University of Poitiers,{{r|lfmr}} where she completed her thesis in 1931{{r|yks|lfmr}} with Paul Montel as chair. Her dissertation was Sur les points de Peano d'une equation différentielle du premier ordre [On the Peano points of a first-order differential equation].{{r|yks}}
Career
Charpentier did postdoctoral studies with George Birkhoff at Harvard University,{{r|yks}}
and was an invited speaker on geometry at the 1932 International Congress of Mathematicians in Zurich.{{r|icm}}
However, she could not obtain a faculty position in France at that time, and instead had to support herself as a teacher at the high school level.{{r|yks}}
She was appointed to her faculty position in 1942,{{r|lfmr}} at the University of Rennes,{{r|yks|escofier}} became full professor there, and retired in 1973.{{r|yks}}
