Louis Pasteur is considered a savior of humanity from extinction, because he was the first to discover vaccination and the vaccine against epidemics, which have always posed a threat to humans, Louis Pasteur was born on the 27th of 1822 to a poor family working in a leather tannery in Dole in France and raised in a town, but they were determined to provide a good education for their son.

He attended primary school when he was nine years old, and at the time showed no particular interest in the sciences. Pasteur traveled to Paris to continue his education, but returned home after homesickness, and enrolled at the Royal College of Besançon where he obtained a Bachelor of Arts, staying To study mathematics, but failed in his final exams.

In 1839 he was admitted to the Collège Royal in Besancon, from which he graduated in 1842 with honors in physics, mathematics, Latin, and drawing. Later, he studied École Normale to study physics and chemistry, specializing in crystals. He served briefly as Professor of Physics at Lycee in Dijon, and later became Professor of Chemistry at the University of Strasbourg.

In 1849, Louis Pasteur was looking for a solution to a problem related to tartaric acid (a chemical compound found in wine fermentation precipitants), as scientists were using the rotation of polarized light to study crystals. Prevention to get rid of these diseases that were causing the death of a large number of people.

His work that undoubtedly saved the most lives was his work on vaccinations. One hundred years before Edward Jenner created the first smallpox vaccine, Pasteur injected chickens with an ancient culture of cholera bacteria. This culture was spoiled, and the chicken did not fall. When Pasteur injected them with fresh cultures of the disease the chickens were immune. This was the first vaccine created in the laboratory.

Pasteur also majored in teaching and graduated from the École Normale Supérieure in 1842. In 1857, Pasteur moved to Paris, where he held a series of professorships before the opening of the Institut Pasteur in 1888. The purpose of the institute was to treat rabies and to study deadly diseases. and contagious,Within the framework of his specialization in biology, microorganisms, mycology and bacteria
Louis Pasteur has become more experienced and is on the verge of making a great discovery that will change the perception of humanity and scientists in the field of studying the immune system.

During the life of Louis Pasteur, it was not easy for him to convince others of his controversial ideas of their time, but he is absolutely correct today. Pasteur struggled to convince surgeons that germs existed and that they were the cause of the disease. Louis Pasteur conducted experiments by exposing the bacilli to oxygen in order to find a cure for anthrax. Indeed, he was able to come up with a vaccine against anthrax.

Some historians disagree with the accepted wisdom regarding Pasteur's discoveries. On the centenary of the biologist's death in 1995, a historian of science, Gerald L. Jason, a book analyzing Pasteur's private notebooks, in 1868 suffered a stroke and paralyzed one side of his body. Although he survived, he was left handicapped. Pasteur died at the age of 72 in Paris after suffering another stroke, but after an institute named after him was built, his body was transferred to the Pasteur Institute in Paris.
