Biography of Louis Pasteur
Louis Pasteur worked tirelessly to develop antidotes and cures to many dangerous illnesses such as anthrax and rabies. He also successfully invented a way to pasteurise milk and make it safe from Tuberculoses.
Louis Pasteur was born on 27th December, 1822 in Dole, Eastern France. He was a conscientious and hard working student, if not exceptional. One of his professors called him ‘mediocre’. He received a doctorate in 1847 and after obtaining posts at Strasbourg, Lille and Paris he spent much time researching aspects of Chemistry. One key discovery related to research on tartrate acid showing the crystals contained a mirror image of right-handed and left handed isomers.
His most important discoveries were in the field of germ study. He showed that germs required certain microorganisms to develop; using this knowledge he found that the fermentation of yeast could be delayed. Louis Pasteur then turned to practical ways of killing bacteria in liquids such as milk.
His process of pasteurisation successfully killed bacteria in milk without destroying milk protein. This was a radical discovery and made drinking milk safe. The process of pasteurisation was named after him and it saved many lives.
Louis Pasteur was a great believer in hard work, never content to rest on his laurels he continued to work very hard in his laboratory to develop more cures. He said in advice to other scientists
“An individual who gets used to hard work can thereafter never live without it. Work is the foundation of everything in this world.”
Louis Pasteur next created a cure for anthrax – a disease that mainly affects cattle. He found that by giving cattle a weakened form of the illness they were able to develop immunity to the illness.
This success encouraged him to develop a cure for rabies – a very common disease at the time. Using similar principles he developed a weakened strain of the disease. Testing on animals affected with rabies was successful, however he was reluctant to test on humans for fear it might not work.
At one point he considered testing on himself by subjecting himself to a rabies and then trying his cure. However, before he could implement his scheme a young boy was brought to him who had been bitten 14 times by a rabid dog. His parents agreed to try the uncertain new technique.
His treatment was a success and news of the treatment soon spread. Over 350 people came to Louis Pasteur for treatment. Louis and his team of scientists worked around the clock to save the people who had contracted rabies.
There was only one failure a ten year old girl Louis Pelletier. Louis knew the dies ease was too advanced when she came, but, he tried nevertheless. The girl died in his arms, with tears in his eyes, the great scientist said to her parents.
“I did so wish I could have saved your little one.”
It was testament to the big heart of the famous scientist he took so much interest in his patients.
in 1888, friends and supporters funded an institute for the treatment of rabies. Louis Pasteur successfully campaigned for better research facilities for scientists. His pleas of more funding were heard by Napoleon III. Louis Pasteur argued that, “Physicists and chemists without laboratories are like soldiers without arms on the battlefield.
Louis Pasteur Death Sentence
Louis died in 1895 at the age of 73. On his last day he remarked,
“I should like to be younger, so as to devote myself with new ardour to the study of new diseases”. Louis Pasteur had great faith in the good nature of humans. He worked tirelessly to deliver real benefits for the treatment of infectious diseases. More than any other person, Louis Pasteur helped to increase the life expectancy of man in the late nineteenth and early twentieth Century.
Achievements of Louis Pasteur
- Process of Pasteurisation making milk safe to drink.
- Cure for rabies.
- Cure for anthrax.
- His principles were used by later scientists such as Frankland, Valley Radot, Emile Duclaux, Descours and Holmes in developing vaccines for dies eases such as typhus, diphtheria, cholera, yellow fever and different strains of plague.
