Théophile-Jules Pelouze

Théophile-Jules Pelouze (also known as Jules Pelouze, Théophile Pelouze, Theo Pelouze, or T. J. Pelouze, pronounced  [pəluz] ; 26 February 1807 – 31 May 1867) was a French chemist.



He was born at Valognes, and died in Paris.

His father, Edmond Pelouze, was an industrial chemist and the author of several technical handbooks. The son, after spending some time in a pharmacy at La Fère acted as laboratory assistant to Gay-Lussac and Jean Louis Lassaigne at Paris from 1827 to 1829. In 1830 he was appointed associate professor of chemistry at Lille, but returning to Paris next year became repetiteur, and subsequently professor at the École polytechnique. He also held the chair of chemistry at the Collège de France, and in 1833 became assayer to the mint and in 1848 president of the Commission des Monnaies. He resigned all his public positions in 1852. [1]

After the coup d'état in 1851 he resigned his appointments, but continued to conduct an experimental laboratory-school he had started in 1846. There he worked with the explosive material guncotton and other nitrosulphates. His student Ascanio Sobrero was the discoverer of nitroglycerin (1847), and another student, Alfred Nobel, was to take that discovery on to great heights in the form of commercial explosives including dynamite. He was a major inspiration for both students.

Though Pelouze made no discovery of outstanding importance, he was a busy investigator, his work including researches on salicin, on beetroot sugar, on various organic acids (gallic, malic, tartaric, butyric, lactic, etc.), on oenanthic ether (with Liebig), on the nitrosulphates, on guncotton, and on the composition and manufacture of glass.

He also carried out determinations of the atomic weights of several elements, and with E. Fremy, published Traité de chimie générale (1847–1850); Abrégé de chimie (1848); and Notions générales de chimie (1853).

His son Eugène-Philippe Pelouze married Marguerite Wilson  [ fr ], a rich heiress, in 1857. The couple purchased the Château de Chenonceau in 1864. Marguerite continued to live there until 1888, when she ran out of money and was forced to sell. [2]

His name is one of the 72 names inscribed on the Eiffel Tower.

Louis Pasteur French chemist and microbiologist

Louis Pasteur was a French biologist, microbiologist, and chemist renowned for his discoveries of the principles of vaccination, microbial fermentation and pasteurization. He is remembered for his remarkable breakthroughs in the causes and prevention of diseases, and his discoveries have saved many lives ever since. He reduced mortality from puerperal fever and created the first vaccines for rabies and anthrax.

Nitrocellulose Highly flammable compound

Nitrocellulose is a highly flammable compound formed by nitrating cellulose through exposure to nitric acid, or to a mixture of nitric acid and another acid, usually either hydrochloric acid or sulfuric acid, or to another powerful nitrating agent. One of its first major uses was as guncotton, a replacement for gun powder as propellant in firearms. It was also used to replace gunpowder as a low-order explosive in mining and other applications.

Asparagine group of stereoisomers

Asparagine, is an α-amino acid that is used in the biosynthesis of proteins. It contains an α-amino group, an α-carboxylic acid group, and a side chain carboxamide, classifying it as a polar, aliphatic amino acid. It is non-essential in humans, meaning the body can synthesize it. It is encoded by the codons AAU and AAC.

Picric acid Explosive chemical compound

Picric acid is an organic compound with the formula (O2N)3C6H2OH. Its IUPAC name is 2,4,6-trinitrophenol (TNP). The name "picric" comes from the Greek πικρός (pikros), meaning "bitter", reflecting its bitter taste. It is one of the most acidic phenols. Like other highly nitrated organic compounds, picric acid is an explosive, hence its primary use. It has also been used in medicine (antiseptic, burn treatments) and dyes.

Marcellin Berthelot French chemist and politician (1827-1907)

Pierre Eugène Marcellin Berthelot was a French chemist and politician noted for the Thomsen–Berthelot principle of thermochemistry. He synthesized many organic compounds from inorganic substances, providing a large amount of counter-evidence to the theory of Jöns Jakob Berzelius that organic compounds required organisms in their synthesis. Berthelot was convinced that chemical synthesis would revolutionize the food industry by the year 2000, and that synthesized foods would replace farms and pastures. "Why not", he asked, "if it proved cheaper and better to make the same materials than to grow them?"
