Her teachers there included Henri Lebesgue and Jacques Hadamard , and she finished her studies in With the encouragement of ENS director Ernest Vessiot she traveled to Oslo to work with Vilhelm Bjerknes , under whose influence she became interested in the mathematics of waves and the work of Tullio Levi-Civita in this subject. She returned to Paris in , married another mathematician, Paul Dubreil, and joined him on another tour of the mathematics centers of Germany and Italy, including a visit with Levi-Civita.

She was the author of two textbooks, one on lattice theory and the other on abstract algebra. As well as her technical publications, Jacotin was the author of a work in the history of mathematics, Portraits of women mathematicians. In semigroup theory, the Dubreil-Jacotin semigroups are named after her, as is the Dubreil-Jacotin—Long equation, "the standard model for internal gravity waves" in fluid mechanics.

Source: Wikipedia. Marie-Louise Dubreil-Jacotin 7 July — 19 October was a French mathematician , the second woman to obtain a doctorate in pure mathematics in France, the first woman to become a full professor of mathematics in France, the president of the French Mathematical Society , and an expert on fluid mechanics and abstract algebra. Marie-Louise Jacotin was the daughter of a lawyer for a French bank, and the grand-daughter through her mother of a glassblower from a family of Greek origin.

Her teachers there included Henri Lebesgue and Jacques Hadamard , and she finished her studies in With the encouragement of ENS director Ernest Vessiot she traveled to Oslo to work with Vilhelm Bjerknes , under whose influence she became interested in the mathematics of waves and the work of Tullio Levi-Civita in this subject. She returned to Paris in , married another mathematician, Paul Dubreil , and joined him on another tour of the mathematics centers of Germany and Italy, including a visit with Levi-Civita.

The Dubreils returned to France again in While her husband taught at Lille, Dubreil-Jacotin continued her research, finishing a doctorate in concerning the existence of infinitely many different waves in ideal liquids , under the supervision of Henri Villat. Following her husband, she moved to Nancy , but was unable to obtain a faculty position there herself because that was viewed as nepotism; instead, she became a research assistant at the University of Rennes.

Its importance and that of her work on the theory of waves meant that she extended work on it until At the start of the new academic year - 32 Paul Dubreil took up an appointment at the University of Lille and Marie-Louise continued to work on her thesis on fluids but began to take an interest in algebra. In she defended her thesis in Paris:- The jury was presided over by Ernest Vessiot.

The other members were Gaston Julia and Henri Villat. Jacques Hadamard came to help with the defence and to sit at her side. Dubreil-Jacotin's interests in algebra had now reached the point where she offered it as a subsidiary subject at her oral. Following the award of a doctorate she went to Nancy where Paul Dubreil now had an appointment at the University.

It would have made sense for the University of Nancy to employ Dubreil-Jacotin too, but they did not wish to employ a husband and wife in the same department. Dubreil-Jacotin, therefore, accepted a position of research assistant at Rennes. On 22 September the Dubreils' daughter Edith was born. Two years later Dubreil-Jacotin was appointed as an assistant lecturer at Rennes.

From to she was an assistant professor at Lyon but also taught courses at Rennes. Lesieur writes that in October [ 3 ] It was at Poitiers that I knew her. I am able to confirm that she began the development of this maths department where she amply filled her role as teacher and researcher. She kept the future in mind by gathering round her a community which comprised Arbault, Croisot, and Lesieur.

This group was later enriched by others. One might reasonably ask how the Dubreils brought up their daughter when Marie-Louise worked in places such as Rennes, Lyon and Poitiers while Paul worked in Nancy. Remember too that these were the years of the Second World War which began around the time that Dubreil-Jacotin became an assistant lecturer in Rennes.

A few days later France was defeated and under German occupation. In fact Edith was brought up in Paris with Paul and Marie-Louise spending weeks about with her [ 2 ] :- The defeat, the occupation and the liberation made these never-ending trips to and from Paris slower and more difficult and dangerous. The train that Marie-Louise took each Tuesday was destroyed by a bloody bombing of the Rennes railway station.

Fortunately this happened on the Mardi Gras holiday of It was in at St Pierre des Corps that she found herself under bombardment. She spent an anxious and sleepless night made worse by twenty-four hours without food.
