The women who defended a thesis in mathematics in France during the interwar period

http://www.2iceshs.cyfronet.pl/2ICESHS_Proceedings/Chapter_18/R-10_Leloup.pdf The women who defended a thesis in mathematics in France during the interwar period Juliette Leloup The Global and the Local: The History of Science and the Cultural Integration of Europe. Proceedings of the 2nd ICESHS Cracow, Poland, September 6–9, 2006 Ed. by M. Kokowski.

Between the two world wars, 242 students of all the French universities have defended a thesis in mathematical sciences. Only five of them were women: Marie Charpentier (from Poitiers), Marie-Louise Dubreil Jacotin and Jacqueline Ferrand (two students of the E.N.S. of Paris), add two astronomers: Edmée Chandon and Rose Bonnet. The problem is that there aren’t a lot of sources giving information about all these women, and more precisely about Edmée Chandon and Rose Bonnet. The only fact we can mention about them is their official appointment as astronomer at the Paris observatory and Edmee Chandon is the first woman in France to be appointed to this. When we study the career and the life of those women, we are forced to be interested in the education of girls in France in their opportunities for education and in its evolution during the interwar.

Even if I haven’t found a lot of pieces of information about Rose Bonnet and Edmée Chandon, we can say that they belong to the community of French astronomers and it is with this appointment that they are quoted in books like World directory of mathematicians. Both have them have defended a thesis in astronomy, one in 1930 (Research into the tides of the Red Sea and in the Gulf of Suez) and the other in 1945 (Spectrums, periods and eccentricity of binaries). But the astronomers have a peculiar position in the French mathematical community. If astronomy is one part of mathematical sciences at this period, it is not promoted by the traditional members of this community.

As for Pierre Fatou, well, he was a bachelor. In his own discrete way, he nevertheless introduces (as an astronomer) a female scientist in this story, the astronomer Rose Bonnet, with whom he used to observe double stars.

Notes: Double Star Notes

http://adsabs.harvard.edu/full/1938Obs....61..332. Notes: Double Star Notes The Observatory, Vol. 61, No. 775, pp 338–339 December 1938

Double Star Notes—A special volume issued by the Observatoire de Paris dealing with double stars has just been issued. It consists of measures of over 500 pairs made by Rose Bonnet with the 30·5 cm. Equatorial of the Paris Observatory and of a catalogue of notes concerning the motion or lack of it exhibited by the pairs measured. The observations were all made between November 1928 and November 1932 and as such will form a welcome addition to the by no means superabundant stock of double star observations made in the Northern Hemisphere in that period. Among them are many successful measures of pairs which are difficult under Western European conditions, including faint Hough and Hussey pairs with separations of half a second or less. It is to be regretted that it has not been found possible to publish these observations sooner, because many orbits have been computed since they were made, and, as the observations were not to be found on card index catalogues, computers have been deprived of the assistance which they would have given in critical cases. The notes are rather dated in some cases, as there are no references to some orbits computed as early as 1934; as luck would have it, there is a full series of references to the unfortunate orbits computed by Voronov. No doubt the criterion for inclusion was availability at Paris at some date in 1934 when the MS. work was closed.

Charles Nordmann and Multicolour Stellar Photometry

After the Pleiades, Nordmann still observed several hundred stars with his photomètre hétérochrome, always attached to the small coudé refractor, as mentioned in the Annual Reports of the Paris Observatory. In 1931, he was given another collaborator, Miss (or Mrs?) Rose Bonnet (1894–?), to replace Le Morvan, who retired the following year and died in 1933. Miss Bonnet made some observations and reductions while working on a thesis on another subject.

A name frequently found in the Reports of the Paris Observatory is the Parvulescu Constantin (1890–1945). He was admitted October 3, 1921 and he remained there until 1925. C. Parvulescu conducted a study of globular clusters, and another on the Perseus cluster. He earned a score of photographic plates of a variable star from oldest clichés Isaac Roberts. John Bosler has initiated the use of Blink-microscope to study the specific movements of the stars and together they initiated a study of two shots, thanks to Henry brothers for the first and Miss Rose Bonnet (now Bonnet-Sainturier ) for the second. In 1924, he contributed to the magazine astronomical work. The same year he published articles in the astronomical Bulletin. December 19, 1925, C. Parvulescu defended successfully at the Faculty of Sciences in Paris, a doctoral thesis on globular clusters (commission: Henry Andoyer, president, Charles Fabry, Elie Cartan, members). He returned to Paris in 1928 and collaborated again in the work of French astronomers. His contributions to the study of galaxies, globular clusters, double stars and the structure of the Galaxy were highly appreciated by specialists.

In those years, other French observers were creating a real "school" around the SAF (Sociedad Astronómica Francesa), which is still recognized today as the most important in the world (just mention the names of other famous observers and discoverers as M. Duruy or P. Baize both contemporaries of Jonckheere). Later this school was able to draw on new wisdom by observers as Rose Bonnet and Edmee Chandon (two of the first professional women astronomers from France, precisely linked to the spectroscopic binary), P. Fatou, A. Pourteau, R. Baillaud, etc.

Orbites de Trois Etoiles Doubles Visuelles

The specific items are preliminary, but their calculation was possible because the companion, who traveled nearly 170 degrees since its discovery, just go through the periapsis in 1952. It was initially calculates the area constant by successive adjustments e curves (t) and p (t) on which seventeen medium sites were selected to trace the apparent ellipse. In particular, based on observations and BAIZE MULLER in 1952 and 1954, the following items were retained. Some important residues in position angle are irreducible because they come from observations near the minimum of the separation, epochs or measures, which are sometimes only estimates, were strong delicates. Did not take into account the extent of ROSE BONNET in 1930 most probably erroneous, nor that of DOBERCK in 1922.

Mais c'est principalement Paul Baize (1901–1995), medecin de son etat, qui a fail la reputation de l'Observatoire de Paris en ce qui concerne les etoiles doubles. Apres le deces premature de Fatou et de Giacobini, l'equatorial de 30 cm passe entre les mains de Rose Bonnet, depositaire des observations inachevees de Fatou. La lunette est peu utilisee, le directeur Ernest Esclangon la confie alors au jeune docteur Baize, auteur de remarquables series de mesures avec une modeste lunette de 108 mm.

Cet observateur sera l'un des plus remarquables que le monde ait connu par l'abondance des mesures (pres de 25,000), leur qualite, et la perspicacite des programmes. A partir de 1939, un nouveau 38 cm est amenage. Une grande partie du lot des binaires, reputees inaccessibles, des americains de Lick est observee a Paris, avec une precision extreme. A tel point que Rose Bonnet, subjuguee par une telle adresse, me confiera un jour: "Les mesures de Paul Baize sont trap bonnes pour etre vraies, il les invente". Non, il ne les invente pas. Les orbites qui en decoulent sous son impulsion et celle de George van Biesbroeck (qui observe de l'autre cote de l'eau) en sont la preuve.

But it is mainly Paul Baize (1901–1995), doctor by profession, who fail the reputation of the Observatoire de Paris in terms of double stars. After the premature death of Fatou and Giacobini the equatorial 30 cm passes through the hands of Rose Bonnet, depositary unfinished observations Fatou. The bezel is not used, the director Ernest Esclangon then entrusted to the young doctor Baize, author of remarkable series of measures with a modest telescope 108 mm.

This observer will be one of the finest that the world has known for the abundance of measurements (nearly 25,000), their quality, and program perspicacity. From 1939, a new 38 cm is feeding. Much of the lot binary inaccessible Reputedly, of American Lick is observed at Paris, with extreme precision. So much so that Rose Bonnet, overwhelmed by such an address, confided to me: "The actions of Paul Baize are good trap to be true, it invents them." No, he did not invent them. The orbits that follow from under his leadership and that of George van Biesbroeck (who observes the other side of the water) are proof.

Où en est l'Astronomie des Etoiles Doubles?

Où en est l'Astronomie des Etoiles Doubles? Couteau, Paul L'Astronomie, Vol. 72, p. 225 1958 http://adsabs.harvard.edu/full/1958LAstr..72..225C

Il en est de meme dans la recherche d'une relation quelconque entre la periode et l'excentricite des binaires. L'excentricite determine l'allongement de l'orbite, elle peut se definir comme etant la distance des foyers d'une ellipse quand on prend le grand axe comme unite. Si on aborde cette question d'une facçon purement statistique, on arrive a la conclusion de Rose Bonnet (5] : «La periode a une certaine tendance a croitre avec l'excentricite.» Mais il est evident que la correlation entre periodes et excentricites depend etroitement de la valeur des orbites calculees.

It is the same in the search for any relationship between the period and the binary eccentricity. The eccentricity determines the elongation of the orbit, it can define as being the distance of the foci of an ellipse when we take the long axis as a unit. If we approach this issue from a purely statistical facçon, we arrive at the conclusion of Rose Bonnet (5): "The period has a tendency to grow with eccentricity." But it is evident that the correlation between periods and eccentricities closely depends on the value of the orbits calculees.

Zur Perioden-Exzentrizitäts-Beziehung spektroskopischer Doppelsterne

http://adsabs.harvard.edu/abs/1950AN....279....1W Zur Perioden-Exzentrizitäts-Beziehung spektroskopischer Doppelsterne Kurt Walter Astronomische Nachrichten, volume 279, p. 1 09/1950

Im Laufe der vergangenen Jahrzehnte ist bei den spektroskopischen Doppelsternen mit dem Anwachsen des Beobachtungsmaterials die Beziehung zwischen Periode und Bahnexzentrizität schluß dieser Arbeit bekannt gewordene Untersuchung dieser Art ist in dem ausfuhrlichen Werk von Rose Bonnet [I] enthalten, in dem mit Hilfe von statistischen Methoden die Existenz reeller Beziehungen zwischen Spektren, Perioden, und Bahnexzentrizität nachwiesen wird. Betreffs der fruheren Untersuchungen zu diesem Gegenstand mag hier der Hinweis auf diese, die fruhere Literatur eingehend berücksichtigende Arbeit genugen.

Ein statistischer Zusammenhang zwischen Periode und Bahnexzentrizität is zwar seit langem bekannt. Daß daruber hinaus das Spektrum der Hauptkomponente in ihm eine wichtige Rolle spielt, geht sowhol aus der Arbeit von R. Bonnet als auch aus der vorliegenden eigenen hervor. Trotz dieser Ubereinstimmung in einem wesentlichen Ergebnis sind aber Methoden und Ziele meiner Bearbeitung andere als die von R. Bonnet und der fruheren Bearbeiter, die sich auf die Darstellung und den Nachweis von statistischen Zusammenhängen beschrankt haben. Schon vor einigen Jahren habe ich darauf hingewiesen ([2], [3], [4]), Daß der Zusammenhängen zwischen Periode und Bahnexzentrizität fur solche System, deren Komponenten der Hauptreihe des Hertzsprung-Russell Diagramms angehoren, eine feinere Struktur erkennen lasse. Dies Behauptung ist damals nur auszugsweise belegt worden. Ein Zweck der vorliegenden Untersuchung ist es, den noch ausstehenden eingehenden Nachweis dafur nachzuholen.

Over the past decades the relationship between period and orbital eccentricity is in the spectroscopic binary stars with the growth of the observational material circuit of this work has become known study of this type is in the export-union work of Rose Bonnet [I] contained in the using statistical methods existence of real relations between spectra, periods, and orbital eccentricity is showed. As to the earlier studies on this subject like here references to those who Earlier literature thoroughly considered working closely moderate.

A statistical correlation between period and orbital eccentricity is indeed known for a long time. In addition, that the spectrum of the main component plays an important role in it, is capital steeped apparent from the work of R. Bonnet and from the present own. Despite this agreement in a substantial outcome but are methods and goals of my processing other than those of R. Bonnet and the earlier editors who have limited to the representation and detection of statistical relationships. A few years ago, I pointed out ([2], [3], [4]), That the relationship between period and orbital eccentricity for such system whose components are the main sequence of the Hertzsprung-Russell diagram are nationals, was indicative of the finer structure. This assertion was at that time only in part occupied. One purpose of the present study is to catch up on outstanding incoming evidence for it.

p6 As for Pierre Fatou, well, he was unmarried. At his discrete way, however, he introduced (as an astronomer) another scientist woman in this story, the astronomer Rose Bonnet, who observed double stars.

p106 On after [Bloch 1931], Fatou research and find collaborators on astronomy questions that double-star interessted, stability of orbits. Just before his death he was considering programs to form astronomers who are not as calculators. We will see the example in Chapter V of Rose Bonnet. Leon Bloch mentions no students mathematicians May.

p158

Part of his observations of double stars (visual) was published in the Journal of Observers in his lifetime [1928d], others are recorded by Rose Bonnet [74], an assistant astronomer who was working with him year [.. .]

[74] On the Fatou advice, Rose Bonnet began the 1928 statistical research on the double star (relations between periods, eccentricities and masses). We know that she followed Frechet's courses in 1928-1929 (the Frechet fund the Academy of Science Archive preserves notebooks in which she took notes of these courses). She continues the observations and the mathematical work after the death of Fatou. In 1937, she was still assistant astronomer when she received a grant from the Academy of Sciences for the publication of a memoir on double stars for which we find no future reference. Besides publishing the observations of Fatou, Rose Bonnet supported a thesis [1945] the double star, the "binaries" on May 3, 1945. A colleague and faithful friend of Pierre Fatou, she dedicated her thesis to the memory of her father, to her mother, her husband, and ... "to the memory of Pierre Fatou, astronomer and mathematician." She continued to work beyond this thesis since the register of readers of the library IHP sees fit in this institution in June 1948 (it is presented by Frechet) and the SMF Bulletin sees become a member of that company in 1955.

"During most of the year, no photometric observations were performed at the Petit Conde, the goal having been made safe in 1939, to be recovered only in the third quarter of 19/10. Moreover, the apparatus had he been provided with its optic, which could not carry out any usual photometric observations; the lens iris indeed demand to be frequently changed in a single evening of observations, which requires full light, and could not accord with the requirements of passive defense."

"In August, the Service has lost its leader Mr. Charles NORDMANN died after a long and painful illness.

Mrs BONNET, observer at the Petit Coudé used most of his time preparing a memorandum on double stars. She is devoted mainly to the study of the influence of the orbital period of the binary various features.

In June 1940, she left with his documents to the designated fallback center: the Observatory of Toulouse, but could not reach it and headed for the Haute-Saône, where she could continue her work until she received ordered to return to the Paris Observatory.

During the third quarter, the Petit Conde was built for physical observation of occultations of stars by the moon. Mr. Tremblot, assistant astronomer, helped Mr. CONSTANT, electrical engineer, has devoted himself to this task; one meets the material difficulties, especially in the acquisition of photoelectric cells with special characteristics."
