(Photo courtesy: Institut Pasteur), 4 major science contributions by Louis Pasteur, the man who discovered pasteurisation, World Rabies Day: All about the deadly disease, In 1854, he started his studies on fermentation, He found that each type of fermentation is carried out by a living microorganism. Microbiology developed as a scientific discipline from the era of Louis Pasteur (1822- 1895) himself. Pasteur's scientific and medical accomplishments include cure for rabies, anthrax, chicken cholera, and silkworm diseases. Louis Pasteur: Works and Discoveries Pasteur's scientific and medical accomplishments include cure for rabies, anthrax, chicken cholera, and silkworm diseases. His pastels and portraits of his parents and friends, made when he was 15, were later kept in the museum of the Pasteur Institute in Paris. A few historians disagree with the accepted wisdom regarding Pasteur's discoveries. Before Pasteur's vaccine was created, bites from rabid animals were treated by cauterizing the wound; rabies almost always developed anyway. Since then, Pasteur directed all his energy on the problem of immunization and applied this principle to several other diseases. You can use it freely (with some kind of link), and we're also okay with people reprinting in publications like books, blogs, newsletters, course-material, papers, wikipedia and presentations (with clear attribution).

Louis Pasteur’s first important discovery in the study of vaccination came in 1879 and was regarding the disease known as chicken cholera. That is it. Biography of Louis Pasteur, French Biologist and Chemist. Furthermore, he insisted that germs could be spread via human contact and even medical instruments, and that killing germs through pasteurization and sterilization was imperative to preventing the spread of disease. Louis Pasteur is best known for inventing the process that bears his name, pasteurization. Still, other critics labeled him a fraud. However, Pasteur made several other very important contributions to science that you should know about. In studying crystals of sodium ammonium tartrate, Pasteur found that although they had the same chemical composition, they did not necessarily have the same structure. Anirudh is a novelist, writer, seo expert and educationist. When the two crystals were together in equal quantity in a solution, the effect of rotation was cancelled. He was the first scientist to create vaccines for fowl cholera; anthrax, a major livestock disease, and rabies. He established without doubt that certain diseases are caused by microorganisms. His work with rabies led him to realize that weak forms of disease could be used as an "immunization" against stronger forms. Between the years 1850 and 1860, … Our editors will review what you’ve submitted and determine whether to revise the article. A Brief Summary of Louis Pasteur’s Germ Theory of Disease. He eventually developed a vaccine which became a saviour for the silk industry. Soon the process was also applied to milk and beer. Louis Pasteur was an average student in his early years, but he was gifted in drawing and painting. He served briefly as a professor of physics at the Lycee in Dijon, and later became a professor of chemistry at the University of Strasbourg. His work in this area, which continued for a further 10 years, is considered by some historians as his “most profound and most original contribution to science”. He pioneered the study of molecular asymmetry; discovered that microorganisms cause fermentation and disease; originated the process of pasteurization; saved the beer, wine, and silk industries in France; and developed vaccines against anthrax and rabies. You have entered an incorrect email address! In 1848, he became a professor of chemistry at the University of Strasbourg, 6. Click here to stay informed and know what is happening around the world with our G.K. and Current Affairs section. Molecular asymmetry.

Louis Pasteur (1822 – 1895) was a French scientist, whose discoveries provided clear evidence relating germs to diseases, paving the way for a golden era in bacteriology in which the causes of many diseases were identified. This fact probably instilled in the younger Pasteur the strong patriotism that later was a defining element of his character. In 1854, Pasteur was appointed as the professor of chemistry and dean of the science faculty at the University of Lille. In 1854, he started his studies on fermentation. Nothing grew in the broths unless the flasks were broken open, showing that living organisms came from outside and were not spontaneously generated. Nevertheless, his accomplishments were tremendous—in particular his anthrax and rabies studies, the importance of handwashing and sterilization in surgery, and most importantly, ushering in the era of the vaccine.
