Transcript

  • 1.  
  • 2. JOSEPH LISTER
  • 3.
    • Joseph Lister
    • Joseph Lister was a British physician who introduced antiseptics into surgery in 1867. He started using carbolic acid dressings in his own surgery work and so cut down the incidence of sepsis which had been shown by Louis Pasteur to be caused by germs. Three years later he claimed that death from surgery had dropped from over 40% to under 15%.
    • He also replaced the original silk thread which was used to stitch wounds with cat gut. The cat gut could be sterilised and was readily absorbed into the body and this improved recovery rates from surgery even more.
    • Thanks to Lister, infection during surgery is unusual rather being the norm as it was in the mid eighteen hundreds.
  • 4. ROBERT OPPENHEIMER
  • 5.
    • John Robert Oppenheimer is know as the father of the atomic bomb. He was an American, theoretical physicist and widely known for his part as scientific director of the Manhattan Project which was the World War 11 attempt to develop nuclear weapons. His team first tested the atomic bomb in New Mexico, and Oppenheimer is said to have quoted from the Bhagavad Gita:
    • ‘ If the radiance of a thousand suns were to burst at once into the sky, that would be like the splendor of the mighty one. Now I have become Death, the destroyer of worlds.’
  • 6. CLARENCE BIRDSEYE
  • 7.
    • Clarence Birdseye is the American inventor who is considered to be the founder of the frozen food industry. In 1922 Birdseye started a series of experiment to see which methods of freezing produced the best fish. As a result of this Birdseye Seafoods Inc was formed. Basically, he has seen how the Inuit in the north had air frozen their fish in seconds in temperatures of -43C and noted how fresh it tasted on thawing. It was his quick freeze machine that really started the modern frozen food industry in 1924.
  • 8. HIPPOCRATES
  • 9.
    • Hippocrates (460-370BC) was a Greek physician who was said to be the father of medicine as we know it today. He was the founder of the Hippocratic School of Medicine. It was this school that first saw the study of medicine as a discipline of its own instead of part of theurgy a philosophy. He is credited with advanced a system for the systematic study of medicine.
  • 10. ANTOINE LAVOISIER
  • 11.
    • Antoine Lavoisier was the father of modern chemistry. He was the first to recognise oxygen and hydrogen as elements in their own right and worked and wrote the very first list of elements. Unfortunately, because he was such a prominent French citizen, he was beheaded during the French Revolution.
  • 12. SIR ALEXANDER FLEMING
  • 13.
    • Alexander Fleming was the Scottish biologist and pharmacologist who discovered the antibiotic, penicillin, in 1928. He made this discovery by accident when he noticed that fungus, in the laboratory, would not grow around a particular kind of mould. He isolated this as being from the penicillium genus.
