Researches on the Molecular Asymmetry of Natural Organic Products

Preface The two lectures which compose this volume were published by the Chemical Society of Paris in a volume entitled “Leçons de Chimie professées en 1860” (Paris, 1861). They give in brief form an account of Pasteur’s brilliant investigations on optically active compounds, and are remarkable for three things; – The fact that they describe the only ways even now ...

How Pasteur Made Nursing Better

19th Century French Nursing

One of the most common occupations in health care is the registered nurse. Registered nurses provide a wide variety of services to patients. They also work very closely with other medical professionals to diagnose patients and assist with treatment. Many of the discoveries of Louis Pasteur related to disease and germ theory revolutionized the nursing and surgical occupations. 19th Century ...

Louis Pasteur, Wine Disease and Napoleon

Louis Pasteur and Napoleon III

For some time during the 19th century, the French wine industry was burdened by different diseases that caused wine to become sour, bitter or flavorless. Knowledge of French wine diseases spread throughout Europe, greatly damaging the wine export sector in France. An English merchant said this just after the treaty agreement between France and Great Britain in 1863: In the ...

The Question of Spontaneous Generation

Redi's Experiment

From Louis Pasteur: His Life and Labours by René Vallery-Radot, 1885 ‘All dry bodies,’ said Aristotle, ‘which become damp, and all damp bodies which are dried, engender animal life.’ Bees, according to Virgil, are produced from the corrupted entrails of a young bull. At the time of Louis XIV, we were hardly more advanced. A celebrated alchemist doctor, Van Helmont, ...

Organic Chemistry and the Idea of the Molecule

Jean Baptiste Dumas

Originally published in Modern Development of the Chemical and Biological Sciences Vol. 4 in 1904. When Berzelius first promulgated his binary theory he was careful to restrict its unmodified application to the compounds of the inorganic world. At that time, and for a long time thereafter, it was supposed that substances of organic nature had some properties that kept them ...

Germ Theory of Disease

Anthrax Spores

Originally published at AnimalResearch.Info Proving the germ theory of disease was the crowning achievement of the French scientist Louis Pasteur. He was not the first to propose that diseases were caused by microscopic organisms, but the view was controversial in the 19th century, and opposed the accepted theory of “spontaneous generation”. Pasteur set out to understand the fermentation process, and ...

The Asymmetry of Naturally Occurring Organic Compounds

Quartz Crystals

Two lectures delivered by Louis Pasteur before the Chemical Society of Paris, on January 20, and February 3, 1860. FIRST LECTURE AT the end of the year 1808 Mains discovered that light which was reflected from opaque or transparent bodies possessed new and surprising properties, which distinguished it from the light that proceeded directly from illuminating bodies. Malus called the ...

Fermentation

Fermentation - Lactic Acid Bacteria

Louis Pasteur first devoted himself to the study of fermentation in 1856, when he is approached by M. Bigo, a local industrialist in Lille, and asked for advice concerning the production of alcohol in beet juice. Apparently Bigo was experiencing large vats of beet juice turning sour instead of alcoholic as expected. Pasteur agreed to help with the problem and ...
