"In 1848, he became professor of chemistry at the University of Strasbourg, where he met and courted Marie Laurent, daughter of the university’s rector in 1849. They were married on May 29, 1849, and together had five children, only two of whom survived to adulthood."

"In 1852, from works on the crystals of tartric acids, Louis Pasteur demonstrated the molecular chirality and also the first explanation of isomerisation."

"Pasteur began to study fermentations and demonstrated the microbiological origin of production of alcohol."

"Following his fermentation experiments, Louis Pasteur performed several experiments to disprove spontaneous generation.“There is no known circumstance in which it can be confirmed that microscopic beings came into the world without germs, without parents similar to themselves.”"

"Pasteur showed that the growth of micro-organisms was responsible for spoiling beverages, such as beer, wine and milk. He invented a process in which liquids were heated to kill microrganisms already present within , pasteurization, patented on 1865."

"In 1865, Louis Pasteur went to Alès, to work on two diseases called pebrine and flacherie who infected silkworms in Southern France. Pasteur developed a system to prevent pebrine allowing the silkworm breeders to separate infected eggs by using a microscope. "

"Beverage contamination led Louis Pasteur to the idea that micro-organisms infecting animals and humans cause disease. He proposed preventing the entry of micro-organisms into the human body, , leading Joseph Lister to develop antiseptic methods in surgery."

" Louis Pasteur used attenuated chicken cholera to immunize poultry, then attenuated anthrax in sheep.This discovery revolutionized work in infectious diseases, and Pasteur gave these artificially weakened diseases the generic name of “vaccines”, in honour of Jenner’s discovery."

"Pasteur produced the first vaccine for rabies by growing the virus in rabbits, and then weakening it by drying the affected nerve tissue. The vaccine had been tested on 50 dogs before its first human trial."

"The rabbies vaccine was used on 9-year-old Joseph Meister, after the boy was badly mauled by a rabid dog. Over 11 days, the boy received 13 inoculations. Three months later , Louis Pasteur examined him and found that he was in good health. Louis Pasteur was hailed as a hero."

"After developing the rabies vaccine, Pasteur proposed an institute for the vaccine. The institute was inaugurated on November 14, 1888 in the presence of the president Sadi Carnot."

"Further a cardiovascular accident, Louis Pasteur died on September 28, 1895, in Marnes-la-Coquette. He was given a state funeral and was buried in the Cathedral of Notre Dame, but his remains were reinterred in the Pasteur Institute ."
