Lorient
Lorient (; ) is a town (''Communes of France, commune'') and Port, seaport in the Morbihan Departments of France, department of Brittany (administrative region), Brittany in western France. History Prehistory and classical antiquity Beginning around 3000 BC, settlements in the area of Lorient are attested by the presence of Megalith, megalithic architecture. Ruins of Roman roads (linking Vannes to Quimper and Port-Louis, Morbihan, Port-Louis to Carhaix) confirm Gallo-Roman presence.

In June 1666, an Ordonnance, ordinance of Louis XIV of France, Louis XIV granted lands of Port-Louis, Morbihan, Port-Louis to the company, along with Faouédic on the other side of the roadstead. One of its directors, Denis Langlois, bought lands at the confluence of the Scorff and the Blavet rivers, and built slipways.

Tonkin
Tonkin, also spelled ''Tongkin'', ''Tonquin'' or ''Tongking'', is an exonym referring to the northern region of Vietnam.

From 1884 to early 1945, this term was used for the French protectorate of Tonkin, composed of only the Northern region. Names "Tonkin" is a Western rendition of 東京 ''Đông Kinh'', meaning 'Eastern Capital'. This was the name of the capital of the Lê dynasty (present-day Hanoi).

Georges Valiron
Georges Jean Marie Valiron (7 September 1884 – 17 March 1955) was a French mathematician, notable for his contributions to analysis, in particular, the asymptotic behaviour of entire functions of finite order and Tauberian theorems. Biography Valiron obtained his Ph.D. from the University of Paris in 1914, under supervision of Émile Borel. Since 1922 he held a professorship at the University of Strasbourg, and since 1931 a chair at the University of Paris. He gave a plenary speech at the 1932 International Congress of Mathematicians in Zürich and was an invited speaker of the ICM in 1920 in Strasbourg and in 1928 in Bologna. His treatise on mathematical analysis in two volumes (''Théorie des fonctions'' and ''Équations fonctionnelles'') is a classic and has been translated into numerous languages under diverse titles and has gone through many new editions, both French and non-French.

Joseph Kampé De Fériet
Marie-Joseph Kampé de Fériet (Paris, 14 May 1893 – Villeneuve d'Ascq, 6 April 1982) was professor at Université Lille Nord de France from 1919 to 1969. Besides his works on mathematics and fluid mechanics, he directed the ''Institut de mécanique des fluides de Lille'' ( ONERA Lille) and taught fluid dynamics and information theory at École centrale de Lille from 1930 to 1969. He devised the Kampé de Fériet functions, which further generalize the generalized hypergeometric function In mathematics, a generalized hypergeometric series is a power series in which the ratio of successive coefficients indexed by ''n'' is a rational function of ''n''. The series, if convergent, defines a generalized hypergeometric function, which ...s. He was an Invited Speaker of the ICM in 1928 at Bologna, in 1932 at Zurich, and in 1954 at Amsterdam. Works * J.

Poncelet Prize
The Poncelet Prize (french: Prix Poncelet) is awarded by the French Academy of Sciences. The prize was established in 1868 by the widow of General Jean-Victor Poncelet for the advancement of the sciences. It was in the amount of 2,000 francs (as of 1868), mostly for the work in applied mathematics. The precise wording of the announcement by the academy varied from year to year and required the work be "in mechanics", or "for work contributing to the progress of pure or applied mathematics", or simply "in applied mathematics", and sometimes included condition that the work must be "done during the ten years preceding the award." 19th century * (1868) Alfred Clebsch * (1869) Julius von Mayer * (1870) Camille Jordan * (1871) Joseph Boussinesq * (1872) Amédée Mannheim, "for the general excellence of his geometrical disquisitions." * (1873) William Thomson, "for his magnificent works on the mathematical theory of electricity and magnetism." * (1874) Jacques Bresse, "for his work i ...

Académie Des Sciences
The French Academy of Sciences (French: ''Académie des sciences'') is a learned society, founded in 1666 by Louis XIV at the suggestion of Jean-Baptiste Colbert, to encourage and protect the spirit of French scientific research. It was at the forefront of scientific developments in Europe in the 17th and 18th centuries, and is one of the earliest Academies of Sciences. Currently headed by Patrick Flandrin (President of the Academy), it is one of the five Academies of the Institut de France. History The Academy of Sciences traces its origin to Colbert's plan to create a general academy. He chose a small group of scholars who met on 22 December 1666 in the King's library, near the present-day Bibliothèque Nationals, and thereafter held twice-weekly working meetings there in the two rooms assigned to the group. The first 30 years of the Academy's existence were relatively informal, since no statutes had as yet been laid down for the institution. In contrast to its British ...

International Congress Of Mathematicians
The International Congress of Mathematicians (ICM) is the largest conference for the topic of mathematics. It meets once every four years, hosted by the International Mathematical Union (IMU). The Fields Medals, the Nevanlinna Prize (to be renamed as the IMU Abacus Medal), the Carl Friedrich Gauss Prize, Gauss Prize, and the Chern Medal are awarded during the congress's opening ceremony. Each congress is memorialized by a printed set of Proceedings recording academic papers based on invited talks intended to be relevant to current topics of general interest. Being List of International Congresses of Mathematicians Plenary and Invited Speakers, invited to talk at the ICM has been called "the equivalent ... of an induction to a hall of fame". History Felix Klein and Georg Cantor are credited with putting forward the idea of an international congress of mathematicians in the 1890s.A.

1862 Births
Year 186 ( CLXXXVI) was a common year starting on Saturday (link will display the full calendar) of the Julian calendar. At the time, it was known as the Year of the Consulship of Aurelius and Glabrio (or, less frequently, year 939 ''Ab urbe condita''). The denomination 186 for this year has been used since the early medieval period, when the Anno Domini calendar era became the prevalent method in Europe for naming years.
