Louis Pasteur was born on December 27, 1822, in the small town of Dôle, France. His father was a tanner, a person who prepares animal skins to be made into leather. The men in Pasteur's family had been tanners back to 1763, when his great-grandfather set up his own tanning business.

Pasteur made his first great discovery in 1848. For a number of years, scientists had been puzzled about organic chemicals such as tartaric acid. A large number of natural organic substances had been found to rotate the plane of polarized light to the left or right, while the apparently identical substances made in the laboratory did not. Pasteur, ...
In 1854, aged 31, Pasteur left Strasbourg to become Dean of the Faculty of Sciences at Lille University – a very senior position for such a young scientist. One of his students at Lille told him about a problem that was bothering his industrialist father. Emile Bigo-Danel’s father owned a distillery in Lille that converted sugar beet to alcohol by ...
In 1857, aged 34, Pasteur returned to the École Normale in Paris as Director of Scientific Studies. No laboratory was available for him and the government said there was no money to fund any research. Determined to continue with his work, Pasteur personally paid for the conversion of part of the École Normale’s attic space to a laboratory and funde...
After spending several years observing the beneficial and harmful effects of microbes on foodstuffs, in 1862 Pasteur invented the pasteurization process. During pasteurization, farm and brewery products such as milk, wine and beer are heated briefly to a temperature between 60 and 100°C, killing microorganisms that can cause them to go bad.
Many scientists continued to believe that simple lifeforms were spontaneously generated; this despite the fact that a number of scientists, such as Theodor Schwann, had carried out work showing that microbes could not simply appear out of nowhere in dirty ponds or decaying meat. When they learned that Pasteur was going to enter the ‘life’ debate, h...
Pasteur’s work in fermentation and spontaneous generation and his discovery that pasteurization could prevent foodstuffs going bad led him to the conclusion that diseases are caused by germs – microscopic organisms. To stay healthy we need to prevent these organisms getting into our bodies. Pasteur recommended using filtration, exposure to heat, or...
In 1863 Pasteur became professor of geology, physics, and chemistry at the Ecole des Beaux-Arts of Paris. Soon he turned his attention to a problem that had very little to do with any of the subjects that he was professor of. The French silkworm industry – indeed the entire European silkworm industry – was being destroyed by a disease nobody seemed...
Pasteur discovered methods of protecting people against two deadly diseases – anthrax (demonstrated in 1881) and rabies (demonstrated in 1885). He devised ways of producing weakened forms of the anthrax and rabies microbes and used these to vaccinate people. When injected into people, Pasteur’s vaccines fired up their immune systems so potently tha...
In 1887 Pasteur founded the institute that bears his name. The Pasteur Institute seeks to continue its founder’s goals of studying microorganisms and treating and preventing diseases. Eight of its researchers have been awarded Nobel Prizes in medicine. Its researchers were the first to isolate the HIV virus and their discoveries have led to better ...
Soon after arriving to become professor of chemistry at Strasbourg, Pasteur met Marie Laurent, daughter of the university’s rector. They married in May 1849. Pasteur was 26 and Marie was 23 years old. Marie married Pasteur knowing and accepting that he was unusually dedicated to his research work – the story goes that on their wedding day someone h...
Louis Pasteur (1822–1895) married Marie Laurent (1826–1910) in 1849. They had 5 children: Jeanne (1850–1859), Jean-Baptiste (1851–1908), Cécile (1853–1866), Marie-Louise (1858–1934) and Camille...
May 29, 2024 · Louis Pasteur (born December 27, 1822, Dole, France—died September 28, 1895, Saint-Cloud) was a French chemist and microbiologist who was one of the most important founders of medical microbiology. Pasteur’s contributions to science, technology, and medicine are nearly without precedent.
