Ecole Polytechnique, the Institute of Egypt, and the suburban Arcueil estates of Laplace and Berthollet. Like Gay-Lussac, the chemists Louis N. Vauquelin, Michel Eugene Chevreul, and Louis Jacques Thenard admitted well-recommended students to their private chemical laboratories. By the 1830s, Dumas and Victor Regnault were training students in larger numbers as part of the expected chemical curriculum. 84...

Stanislao Cannizzaro (1826-1910) was born in Palermo, Sicily, the son of the chief of police. He studied at the University of Pisa under Rafaelle Piria and also worked in Paris with Michel-Eugene Chevreul. As a youth, he took part in the Sicilian revolution of 1B48 and was at one point condemned to death. He was professor of chemistry at the universities of Genoa, Palermo, and Rome and is best known for being the first to clarify the distinction between atoms and molecules. 

Michel-Eugene Chevreul (1786-1889) was bom in Angers, France. Educated at Paris, he became professor of physics at the Lyc e Charlemagne in 1813 and professor of chemistry in 1830. Chevreul s studies of soaps and waxes led him to patent a method for manufacturing candles. He also published work on the psychology of color perception and of aging. All of France celebrated his 100th birthday in 1886. 

Born in Palermo, Sicily, in 1826, Stanislao Cannizzaro began medical studies at the University of Palermo before moving to Pisa to study chemistry. However, when the Sicilian revolt broke out in 1848, Cannizzaro took part in the capture of Messina. The failure of the revolt forced Cannizzaro to flee to France, where he continued his studies in chemistry at the laboratory of Michel-Eugene Chevreul. In 1851, he returned to Italy and accepted a teaching position in Alessandro. 

Michel-Eugene ChevreuI was a chemist whose career spanned the greater part of the nineteenth century. He was born in Angers, France, on August 31, 1786, and died in Paris on April 9, 1889. Chevreul s fether was a well-known physician. Raised in the midst of the terror of the French Revolution, ChevreuI witnessed much violence and suffering. As a result, he maintained a lifelong aversion to politics and at an early age decided to devote his life to chemistry.

The first description of cholesterol was written by a French scientist by the name of Poulletier de la Salle (dates not available), who isolated the compound from gallstones, a rich source of the substance. In 1816, de la Salle s compatriot Michel Eugene Chevreul (1786-1889) suggested the name of cholesterine for cholesterol, combining the French words for... 

FIGURE 327. This is the color wheel, in black and white, pioneered during the nineteenth century by the famous early organic chemist Michel Eugene Chevreul (1786 1889), who first published in 1806, and later published his final paper at the age of 97 and sent his last scientific communication to his beloved Musium d Histoire Naturelle at the age of 102. 

Soap is the earliest surfactant. The earliest soap was made by boiling fats together with ashes of plant, which dated as early as 2800 B.C. in ancient Babylon. In 1823, Michel Eugene Chevreul, a French chemist, worked out the structure of fats... 

Von Liebig came to Paris to study with Louis-Jacques Thenard (1777-1857), Gay-Lussac, Michel-Eugene Chevreul (1783-1886) and Nicolas Vauquelin (1763-1829). Returning to the University of Giessen, in Germany, he became a university professor at the age of 21, something quite unique in history. 

The French chemist Michel Eugene Chevreul (1786-1889) spent the first part of an incredibly long professional life in an investigation of fats. In 1809, he treated soap (manufactured by heating fat with alkali) with acid, and isolated what are now called fatty acids. Later, he showed that when fats... 

The principal initiator and first president of what was at first more of a club rather than a scientific society was Giacomo Arnaudon, from Torino, at that time serving as preparateur to Michel Eugene Chevreul at the Gobelins... 

Hence, it is not surprising that chemists continued to identify and classify plant substances in the traditional naturalistic and artisanal way well into the nineteenth century. Chapter 15 discusses the continuity of ambiguities in chemists practice of classifying plant materials before and after the Chemical Revolution. It further deals with the gradual attempts of some French chemists to implement the Lavoisierian approach in their practice of classifying organic substances, and the criticism of these attempts by the Swedish chemist Jons Jacob Berzelius and the French chemist Michel Eugene Chevreul.
