Hippocrates was a Greek doctor who came up with the theroy of the 4 HUMOURS.

  • He was the first doctor to observe people before making a diagnoses.
  • He created the Hippocratic Oath which was a document that all doctors had to sign. It stated that doctors had to keep the patients symptoms and treatments confidential, they were never allowed to use magic whilst treating patients and that making people healthy was in their best interest and they did not become a doctor to become wealthy.
  • He creates a series of books called the 'Hippocratic Collection of Books'. The books were a diary of all of the symptoms and treatments he had given so doctors in the future could learn from it.
  • He was the first doctor to encourage natural treatments instead of praying to God.

Claudius Galen

Galen was a Roman doctor who developed the theory of the 4 Humours by using OPPOSITES.

  • The theory of Opposites was part of the treatments developed for the 4 humours. If a person had too much phlegm in their system then they were too cold and the opposite of cold is hot. Galen would use hot ingrediants such as chili to balance their humours.
  • Galen also had a big influence on ANATOMY AND DISSECTION. He was only able to carry out dessection in Alexandria because it was not allowed anywhere else in Italy.  He believed that physicians should try and learn as much as possible about the bodies structure.
  • Galen had to dissect animals instead of humans but he still proved alot about the workings of the body, He proved the brain, not the heart, controlled speech. He also proved that the ateries, not just the veins, carried blood around the body.
  • Although he did make some mistakes as humans and pigs bodies slightly differ, The biggest mistake was that the liver made new blood from food.
  • Galen also created a series of books, similar to Hippocrates.

Andreas Versalius

Versalius was a doctor in the Rennaissance and he proved Galen could be WRONG!

  • No doctors had even questioned the finding of Galen until Versalius was around.
  • Some of his discoveries included that; the jaw had one bone, not two as Galen had described, the breast bone had 3 parts, not 7 and blood did not flow through the heart by invisible holes.
  • He angered the church by saying that men and women have the same number of ribs,
  • He was helped by the use of printers. This multiplied his bookks and findings. Without the printer his ideas and findings may not have had such an impact.

WIlliam Harvey

Harvey was a doctor in the Renaissance period and worked on finding things about the BLOOD.

  • His main discovery was that the heart acted as a pump to pump blood around the body. He dissected cold blooded animals to see the heart in action and human hearts to see how the heart worked.
  • He calculated the amount of blood going into the arteries each hour. He discovered this was 3 times the weight of a man.
  • His idea was influenced by the mechancial water pumps in London and this gave hime the idea that the blood may be pumped around the body.

Ambroise Pare

Pare was a doctor in the Renaissance period and discovered alot about WAR WOUNDS  and SURGERY.

  • His main discovery was using silk ligatures to seal wounds caused by amputations. Each thread sealed a blood vessel and this was a lot less painful than the previous treatment of cauterising.
  • He changed the treatment for gunshot wounds, He rubbed egg yolks, rose oil and turpentine on the wounds.
  • He started to create false limbs for soliders who had lost them in  the war.
  • The printing press meant that his discoveries spread much quicker than surgeons of the medival era,

Louis Pasteur

Pasteur developed the GERM THEORY but he didn't know the science behind it.

  • He first proved that beacteria was responsible for souring milk, wine and beer. He proved that you could remove the bacteria by boiling the substance and cooling it back down again. This process is called pausteriation.
  • He also came up with the Germ Theory.
  • He proved that germs attack the body from the outside.
  • This theory helped him to explain what caused many diseases and  this meant he was able to work out the treatments for them. These disease included; Thphoid, Tuberculosis, Diptheria and Tetanus.
  • He also created a vaccine for rabies. He gave it to a boy who had rabies and he survived.

Robert Koch

Koch came up with the method of DIFFERENTIATING BACTERIA.

  • He created a method which included staining the bacteria to differentiate the bacteria.

Alexander Fleming, Howard Florey and Ernst Chain

Fleming was a 20th Century doctor who discovered PENICILLIN,

  • Fleming did this by accidently leaving a petri dish full of bacteria on the side and when he came back it had penicillin growing next to it killing the bacteria. However although he did further research he had to stop this ebcause he could not get the funding because of WW2.
  • 9 years later Florey and Chain started to develop penicillin. They grew it and tested it on a mouse. It was successful but the government only funded them £25.
  • After months of growing penicillin in containers Albert Alexander was dying of septicaemia. He gave them the pencillin and he was starting to get better but they run of bacteria and Albert died.
  • Later Florey and Chian recieved the funding to mass produce pencillin for WW2. On D-Day 1944 over 2.3 million does of pencillin were used.
