Charles_Riquier

Charles Edmond Alfred Riquier (19 November 1853, Amiens – 17 January 1929, Caen) was a French mathematician.Riquier matriculated in 1873 at the École Normale Supérieure (ENS) where he received his agrégé in mathematics in 1876. He taught from 1876 to 1878 at the Lycée de Brest and then from 1878 to 1886 at the Lycée de Caen and from 1886 to 1924 at the Université de Caen, where he retired as a professor emeritus.
After a brief leave of absence from the Lycée de Caen, Riquier received his doctorate in mathematics in 1886 from ENS at Paris with dissertation Extension à l’hyperespace de la méthode de M. Carl Neumann pour la résolution de problèmes relatifs aux fonctions de variables réelles à laplacien nul. His thesis committee consisted of Hermite (as chair), Darboux, and Picard.In 1910 he was awarded the Poncelet Prize. In 1920 he was elected to the French Academy of Sciences as the successor to Hieronymus Zeuthen. (Eugène Fabry was elected Riquier's successor in 1931.)
Riquier, Maurice Janet, Joseph Miller Thomas, Joseph Fels Ritt, and Ellis Kolchin were among the greatest pioneers of differential algebra and symbolic computation for systems of partial differential equations.

Jules_Henri_Debray

Jules Henri Debray (26 July 1827, in Amiens – 19 July 1888, in Paris) was a French chemist.
In 1847 he began his studies at the École Normale Supérieure in Paris, and several years later became an instructor at the Lycée Charlemagne (1855). From 1875 onward, he taught classes in chemistry at the École Normale Supérieure, where in 1881 he succeeded Henri Étienne Sainte-Claire Deville as professor of chemistry.He is best remembered for his collaborative research with Sainte-Claire Deville involving the properties of platinum metals, in particular, the melting of platinum and its alloys. Their process for melting platinum remained the chosen method until induction furnaces became available decades later. In 1860, the two scientists were the first to melt an appreciable quantity of iridium.During his career, Debray served as an assayer for the Bureau de Garantie of Paris, was vice-president of the Société d'Encouragement pour l'Industrie Nationale and was a member of the Académie des sciences.

Pierre_Yvert

Pierre Yvert (30 September 1900 – 13 January 1964) was a French philatelic editor. Son of Louis Yvert, one of Yvert et Tellier's founders, he was manager of magazine L'Écho de la timbrologie and of many philatelic associations.

Charles_Tellier

Charles Tellier (29 June 1828 – 19 October 1913) was a French engineer, born in Amiens. He early made a study of motors and compressed air. In 1868, he began experiments in refrigeration, which resulted ultimately in the refrigerating plant, as used on ocean vessels, to preserve meats and other perishable food. In 1911, Tellier was awarded the Joest prize by the French Institute and, in 1912, he was made Chevalier of the Legion of Honour. He wrote Histoire d'une invention moderne, le frigorifique (1910).
Tellier died impoverished in Paris. Dimethyl ether was the first refrigerant, in 1876, Charles Tellier bought the ex-Elder-Dempster a 690 tons cargo ship Eboe and fitted a Methyl-ether refrigerating plant of his design. The ship was renamed Le Frigorifique and successfully imported a cargo of refrigerated meat from Argentina. However the machinery could be improved and in 1877 another refrigerated ship called Paraguay with a refrigerating plant improved by Ferdinand Carré was put into service on the South American run.

Simone_Renant

Simone Renant (19 March 1911 – 29 March 2004) was a French film actress. She appeared in more than 40 films between 1934 and 1983. She was born in Amiens, France and died in Garches, France.
