Paris, France 1802 visit

Raymond Daudel was bom in Paris, France, on February 2, 1920, the only child in a middle-class French family. As early as eight he was fascinated by scientific experiments, and at ten he was deeply impressed by a visit with his father to a Museum of Chinese Arts in Paris. From these early experiences he kept, throughout his life, a common interest in the arts and the sciences. 

In parallel he was from 1950 at Stanford University a Lecturer in aeronautical engineering, a professor there from 1959, and from 1975 to 1992 professor of applied mechanics. He was a Guggenheim Fellow in 1954, a visiting professor to University of Paris, France in 1958, and an exchange visitor of the National Academy of Sciences to the USSR in 1965. He was in 1976 elected to the National Academy of Engineering, was a member of the American Physical Society APS, and the American Academy of Arts and Science AAAS. 

Carnot soon realized that he did not have the temperament of a soldier and in 1818 left the army. After leaving the army Carnot took up residence in his father s former Paris apartment, and was presumably supported by his family whiile he attended classes at Sorbonne, the College de France, and the Conservatoire des Arts et Metiers. He also frequently visited factories and workshops, both to see steam engines actually in use, and to learn more about the economics of such industrial use of energy. There were rumors that he did at least on a lew occasions receive some consultant s fees for his advise, but there was no clear documentary evidence of this. In 1827 he returned to active militaiy seiwice with the rank of captain, but this lasted only a little more than a year. He resigned in 1828 and died of cholera four years later in Paris. 

When Berzelius visited Paris in 1818, he inspected a lead-chamber plant in which sulfuric acid was made by burning sulfur with saltpeter, the daily output being 300 pounds. The acid was condensed first in a lead caldron and then in a platinum boiler. This plant had three pairs of lead chambers and two small platinum kettles, each of which had a capacity of from 2 to 21/a gallons. The cost of the two platinum kettles was 9000 francs (15). 

Visiting Scientist, Institut de Physique Nucleaire, Universite de Paris, Orsay, France, September 1983. 

Jean-Marie Lehn has a joint appointment as Professor at the Institut Le Bel, Universite Louis Pasteur in Strasbourg and at the College de France in Paris. Donald J. Cram (1919-2001), Jean-Marie Lehn (b. 1939), and Charles J. Pedersen (1904-1989) received the Chemistry Nobel Prize in 1987 for their development and use of molecules with structure-specific interactions with high selectivity. The conversation with Professor Lehn took place during a brief Budapest visit of his on May 8, 1995. The interview was squeezed in between a press conference and a lecture, and the schedule was running late. ... 

Proust completed his studies in Paris but at the age of 24 he moved to Spain, the country where he would spend most of his professional career. However, his first visit to Spain was fairly short and in 1780 he was back in Paris, where he worked with Pilatre de Rozier and Jacques Charles (see above) on aerostatic experiments. These ventures culminated in the ascent of Proust and Pilatre in a balloon filled with hydrogen over Versaille in June 1784, watched by a public that included the Kings of France and Sweden and their courtiers. 

This work was supported in part by National Science Foundation Grant No. CHE 9311401. Some of it was performed while the author was a visitor in the CNRS group of Jean-Michel Launay and Maryvonne LeDorneuf at the Department of Atoms and Molecules in Astrophysics, Paris Observatory, Meudon, France, during part of 1992. He wishes to thank them for their kind hospitality and the CNRS for support during that visit. 

In 1812 Berzelius was invited by Berthollet to visit Paris but war broke out between France and Sweden, so he went instead to England, where he visited Davy. He gives an amusing account of his reception. He says Davy took a criticism of his chlorine theory seriously. The two corresponded from 1808 till 1813, when a criticism of Davy s Elements of Chemical Philosophy put an end to the friendship. Berzelius had Davy s letters bound and wrote on the flyleaf Humphry Davy, Pres. Roy. Soc. Le plus grand chimiste de son sifecle. Berzelius was much impressed by Alexander Marcet s experimental lectures... 

Fig. 6. Albert Policard visiting the Silicosis Research Institute Rheinpreusseri". Born in Paris, he studied medicine at the ficole de Service de Sant6 militaire in Lyons. In 1913 he became reader in histology. After World War I he was nominated professor of histology at Lyons and after his superannuation became organiser of a laboratory of biology applied to pulmonary silicosis at the Charbonnages de France from 1950-1968. In 1963 he was elected a non-resident member of the Acad6mie des Science in Paris...
