Louis Pasteur

  1. 1. Louis Pasteur A gallery prepared by Adrianna Owcarz
  2. 2. <ul><li>Louis was born on 27th December 1822, in </li></ul><ul><li>Dole, France. </li></ul><ul><li>His father's name was Joseph. </li></ul><ul><li>He was a soldier in Napoleon's army and his </li></ul><ul><li>job was a gravedigger. </li></ul>
  3. 3. <ul><li>Louis' wife was Maria Laurent. They got married in 1849. They had 4 children, two of them died in the childhood. Louis Pasteur was a great patriot and a good Catholic. </li></ul>
  4. 4. <ul><li>As a child Louis loved to paint. </li></ul><ul><li>His paintings were amazing. </li></ul><ul><li>But at the age of 19, he decided to start </li></ul><ul><li>a scientific career. </li></ul>His first interest . . .
  5. 5. <ul><li>He finished school in Besançon. Then he studied in </li></ul><ul><li>Paris École Normale Supérieure. He studied physics </li></ul><ul><li>and chemistry. In the course of his study, he was not an </li></ul><ul><li>extraordinary student. In 1846 he received a Ph.D. </li></ul><ul><li>in chemistry. </li></ul>His education
  6. 6. <ul><li>He worked as a professor at the University of </li></ul><ul><li>Strasbourg, Lille and Paris. </li></ul>Pasteur's job
  7. 7. <ul><li>He made the first discovery in 1848 in the field </li></ul><ul><li>of crystallography. Using the glass and </li></ul><ul><li>tweezers, Pasteur carried out the </li></ul><ul><li>observation of crystals tartrates. It </li></ul><ul><li>showed that there were two of the characters, </li></ul><ul><li>which were their mirror reflections. In this way, Louis </li></ul><ul><li>discovered the secret construction of tartratic acid. </li></ul>The first discovery
  8. 8. <ul><li>In 1854 Pasteur concentrated on the fermentation process. Other famous chemists believed that the fermentation was a chemical process. Louis denied it. He came to conclusion that it was a biological process, during which yeast was reproduced. Louis published his conclusion in his book in 1857. </li></ul>The next great discovery of Louis
  9. 9. <ul><li>During studies on fermentation Pasteur concluded </li></ul><ul><li>that: 'there is a category of creatures that breathe </li></ul><ul><li>so actively that receive oxygen from certain </li></ul><ul><li>compounds, which are subject to the </li></ul><ul><li>slow decomposition'. </li></ul><ul><li>Pasteur discovered anaerobic micro-organisms </li></ul><ul><li>and gave scientific basis for the process used for </li></ul><ul><li>centuries, for example in the manufacture of wine, </li></ul><ul><li>beer and strong alcohol. </li></ul>The discovery of anaerobic micro-organisms.
  10. 10. <ul><li>Luis undertook many highly </li></ul><ul><li>innovative experiences. Thanks to them, he </li></ul><ul><li>showed that atmospheric air contains micro </li></ul><ul><li>organisms and that can also be found in substances </li></ul><ul><li>such as sugared water, which comes into </li></ul><ul><li>contact with the air. He heated and boiled water in glass </li></ul><ul><li>flasks with curved neck. It turned out that life </li></ul><ul><li>appears in the flasks in the liquid, until the contact with the air. </li></ul>Micro-organisms in the ambient air
  11. 11. <ul><li>Louis explained the causes of spoilage of wine turns into a vinegar or bitter. He proved that this process was the result of bacterial decomposition. He wanted to remedy this by adding variety of forms to the wine. He discovered a better way to do this. Since then, the process is called pasteurization. </li></ul>Pasteurisation ...
  12. 12. In 1880 Louis managed to isolate the microbes that cause cholera in poultry . It was the first attempt to induce immune reaction. He wanted to manufacture the vaccine. Pasteur state birds of a culture of cholera bacteria. He concluded that the birds did not fall ill. Then, he carried out a further experiment, which showed that the activity of cholera germs were weakened with the progress of time. Pasteur discovered the general principle of the acquisition of resistance by organisms. To produce vaccines against cholera
  13. 13. Then, the vaccine against rabies was developed. Up to that time, the disease was considered to be terrible and almost incurable. Pasteur immunized his dogs after implantation of the weakened bacteria. Vaccine against rabies
  14. 14. <ul><li>In 1885 a small boy, who had been attacked by the dog affected with rabies, was brought to Pasteur. The scientist decided to use the vaccine. Pasteur saved the boy and covered himself with honour. </li></ul>Unusual act ...
  15. 15. He died in St. Cloud on 28th September 1895. He was buried in the Cathedral of Notre-Dame in Paris. Currently, the remains of Louis Pasteur are stored in the crypt in the Pasteur Institute of Paris.
  16. 17. <ul><li>When was Louis Pasteur born ? </li></ul><ul><li>Who was his father? </li></ul><ul><li>Who did he marry? </li></ul><ul><li>How many children did he have ? </li></ul><ul><li>What did he do in his childhood ? </li></ul><ul><li>Where did he study ? </li></ul><ul><li>Where did he work ? </li></ul><ul><li>What did he disover? </li></ul><ul><li>When did he die ? </li></ul><ul><li>Where was he buried? </li></ul>Quiz !
