Английская Википедия:Charles Thilorier
Charles-Saint-Ange Thilorier was a student at the École polytechnique in the class / year of 1815, who was mistakenly believed to have been the first person to create solid carbon dioxide ("dry ice"). Actually, a French inventor, Adrien-Jean-Pierre Thilorier (1790–1844), discovered dry ice.
Unfortunately, in almost all of his technical articles, Adrien Thilorier gave his name simply as "Thilorier";[1] similarly, whenever others referred to him in technical articles, his name was also given only as "Thilorier". This impeded efforts by scholars to identify him subsequently.[2] The confusion was compounded when Paul Thénard wrote a biography of his father, Louis Thénard, a French chemist:[3] In 1835, Adrien Thilorier had created dry ice by spraying liquid carbon dioxide into a glass vessel. He had thought that the dry ice was merely snow; that is, water vapor from the atmosphere which had condensed as a result of the cold that the evaporation of the liquid carbon dioxide had produced. Louis Thénard had explained to Thilorier that his "snow" was actually solidified carbon dioxide.[4] In a footnote of Louis Thénard's biography, Paul Thénard identified the "Thilorier" who discovered dry ice as "Charles-Saint-Ange Thilorier", a student at the École polytechnique in the class of 1815.[5] This (mistaken) identification was mentioned by Duane H. D. Roller, a graduate student at Harvard University, in a paper that was published in 1952.[6] Consequently, many sources claim that Charles-Saint-Ange Thilorier discovered dry ice.
Adrien-Jean-Pierre Thilorier was an employee of the French Post Office in Paris who invented, among other things, an oil lamp, a gas compressor, and an apparatus for producing liquid carbon dioxide. It was a French scholar who revealed that he had discovered dry ice.
During the 1960s, Madeleine Ambrière-Fargeaud, a scholar in France, was trying to identify the person who served as the model for a "mad scientist" character, Balthazar Claës, in Honoré de Balzac's novel La Recherche de l’absolu (The Quest of the Absolute). Her research suggested that Claës was inspired (in part) by Adrien-Jean-Pierre Thilorier.[7] By 2003, Joost Mertens, a Dutch historian of science, had verified many of the findings that Ms. Ambrière-Fargeaud had made about Thilorier.[8]
That "Thilorier" is actually Adrien-Jean-Pierre Thilorier is proved by French government documents, especially patents. In 1826, he was granted a patent for a "hydrostatic lamp"; the patent lists his name as "Thilorier (Adrien-Jean-Pierre)" of Paris.[9] His 1831 patent for a gas compressor also lists his name as "Thilorier (Adrien-Jean-Pierre)" and describes him as an employee of the "Administration des postes" (i.e., the Post Office) in Paris.[10] In 1832, the Bulletin of the laws of the kingdom of France also lists him as "Thilorier (Adrien-Jean-Pierre)" and as an employee of the Post Office, who resided at number 21 on the Place Vendôme in Paris, and as the inventor of a gas compressor.[11]
