Charles-Louis Barreswil
Charles-Louis Barreswil (13 December 181722 November 1870) was a French physiologist and biochemist who was among the first to investigate the process of digestion in humans and also a range of other chemical applications including photographic and printing processes. Barreswil was born to Madeleine Desiree Cambon and Cyr Magloire Barreswil who worked at the Château de Versailles. Barreswil studied chemistry under Pierre-Jean Robiquet (1780–1840) and Théophile-Jules Pelouze (1807–1867) in Paris. He joined the laboratory headed by Pelouze and collaborated with Claud Bernard (1813–1878) from 1848. Their experiments included studies on the assimilation of nutrients. Their approach was to feed a pure substance and examine if it was also produced in the urine or faeces. They experimented on dogs as well as themselves. They came to the conclusion that the gastric juice was acidic but rejected the possibility of HCl and suggested instead that it was lactic acid. In 1848, they det ...

Pierre Jean Robiquet
Pierre Jean Robiquet (; 13 January 1780 – 29 April 1840) was a French chemist. He laid founding work in identifying amino acids, the fundamental building blocks of proteins. He did this through recognizing the first of them, asparagine, in 1806, while working as an assistant for Louis Nicolas Vauquelin. He likewise laid founding work in the industry's adoption of industrial dyes, with the identification of alizarin in 1826, and in the emergence of modern medications, through the identification of codeine in 1832, an opiate alkaloid substance of widespread use with analgesic and antidiarrheal properties. Robiquet was born in Rennes. He was at first a pharmacist in the French armies during the French Revolution years, and became a professor at the École de pharmacie in Paris, where he died. Notable scientific achievements were among other things his isolation and characterization of properties of asparagine (the first amino acid to be identified, from asparagus, achieved. In ...

Théophile-Jules Pelouze
Théophile-Jules Pelouze (also known as Jules Pelouze), ; 26 February 180731 May 1867) was a French chemist. Life He was born at Valognes, and died in Paris.

Claude Bernard
Claude Bernard (; 12 July 1813 – 10 February 1878) was a French physiologist. I. Bernard Cohen of Harvard University called Bernard "one of the greatest of all men of science". He originated the term ''milieu intérieur'' and the associated concept of homeostasis (the latter term being coined by Walter Cannon). Life Bernard was born in 12 July 1813 in the village of Saint-Julien, near Villefranche-sur-Saône. He received his early education in the Jesuit school of that town, then attended college at Lyon, which he soon left to become assistant in a druggist's shop.

Despite this, after his death Cardinal Ferdinand Donnet claimed Bernard was a fervent Catholic, with a biographical entry in the ''Catholic Encyclopedia''. His leisure hours were devoted to the composition of a vaudeville comedy, and the success it achieved moved him to attempt a prose dra ...
