Louis Pasteur (December 27, 1822 – September 28, 1895) was a French chemist and microbiologist renowned for his discoveries of the principles of vaccination, microbial fermentation and pasteurization. He is remembered for his remarkable breakthroughs in the causes and preventions of diseases, and his discoveries have saved countless lives ever since. He reduced mortality from puerperal fever, and created the first vaccines for rabies and anthrax. His medical discoveries provided direct support for the germ theory of disease and its application in clinical medicine. He is best known to the general public for his invention of the technique of treating milk and wine to stop bacterial contamination, a process now called pasteurization. He is regarded as one of the three main founders of bacteriology, together with Ferdinand Cohn and Robert Koch, and is popularly known as the “father of microbiology”. Pasteur also made significant discoveries in chemistry, most notably on the molecular basis for the asymmetry of certain crystals and racemization….” http://en.wikipedia.org/wiki/Louis_Pasteur
" On 27 December, 1822 Louis Pasteur was born in a poor family of tanners in Dole, situated in the Jura region of France. Louis was brought up in Arbois town in eastern France. He received his degrees in Letters and Mathematical Sciences. Soon after this he got admitted to École Normale Supérieure, an elite college.
In 1848 Pasteur became the professor of physics at Dijon Lycée. He stayed here for a short period before switching off to University of Strasbourg as a professor of Chemistry. He met and found his love in Marie Laurent, daughter of the university’s rector, in 1849. On 29 May in the same year Pasteur married Marie with whom he had 5 children out of which only two survived to become adults. Pasteur’s three children died of typhoid. Losing his children was very tragic in Pasteur’s life which also made him firm in discovering cures for diseases like typhoid. Pasteur’s personal losses left a deep scar within him inspiring him to do something for incurable diseases and symptoms….” http://www.thefamouspeople.com/profiles/louis-pasteur-145.php
