Louis Pasteur was born on December 27, 1822 in Dole, France to a catholic family of a poor tanner. He was the third child of Jean-Joseph Pasteur and Jeanne-Etiennette Roque. Pasteur started primary school in 1831. He was an average student in his early years.
Pasteur attended secondary school at the College d'Arbois. In October 1838 he left Paris to join the Pension Barbet, however left in November. 1839 he entered the College Royal at Besancon to study Philosophy and earned his Bachelor of Letters degree in 1840. at the college he continued his degree science course with special mathematics.
In 1841, I failed my first exam! But I managed to pass the general science degree in 1842. However my score was only mediocre.
1842, Pasteur got into Ecole Normale Superieure (low ranking) however he decided not to continue and try again next year. He went back to the Pension Barbet to study for the test. 1843, he passed the test with high ranking and entered the school.
In 1845 he received his master of science degree. 1846 he was ppointed professor of physics at the college de Tournon but chemist - Antoine Jerome Balard wanted him as a graduate labratory assistant. He joined Balard and started his researd on crystallography. In 1847 he submitted his two theses, one in chemistry the other in physics.
I courted my wife, Marie Laurent in 1849. We had 5 children but 3 died of Typhoid.
1856, local wine manufacturer M. Bigot asked Pasteurs advice because his alcohol kept souring. Pasteur found out that if the alcohol was heated it could control the micro-organisms that were responsible for the souring. However many people in those days thought his idea was too revolutionary.
Pasteur appointed prof. of Chemistry at the University of Strasbourg in 1848, he became the chair of chemistry in 1852. In 1854, he was named dean of the new faculty of sciences at the University of Lille. He began his studies on fermentation.
He did other work to. Including researching the immunology and vaccination of Chicken cholera, Anthrax, Swube erysipelas and rabies. For chicken cholera he inoculated a set of chickens with virulent bacteria that killed other chickens, and witnessed the inoculated chickens survive. He concluded that if you injected chickens with the virulent bacteria they would survive chicken cholera.
In the 1870s, he applied the same method to Anthrax as he did the Chicken Cholera. Pasteur cultivated blood of animals infected with anthrax and inoculated other animals with the bacteria, and realised that because the animals injected with anthrax became ill with anthrax, that the cause was bacteria. Pateur eventually worked out that animals should not be buried in the fields because of anthrax bacteria in earthworms excretement.
Pasteur died on September 28, 1895, near Paris. He was buried in the cathedral of Notre Dame, but his remains were reinterred in the Pasteur Institute in Paris.
Pasteur helped modern medicine greatly as he also encouraged doctors to sanitise hands and equipment before surgery. Many of his vaccinations also help aid the safety of people nowadays and people in the past.
