Louis Pasteur
Robert Koch
Joseph Lister
William Morton

2. John Dalton
Dalton → school teacher that stated that atoms are the smallest parts of elements.
Developed a system of atomic weights
Helped lay the foundation for modern atomic theory

3. Michael Faraday
Faraday → demonstrated that magnetism can produce electricity.
His ideas helped discover that mechanical power can be converted to electrical power.
Also helped invent electric generators

4. Wilhelm Roentgen Roentgen → helped discover X-rays in 1895.
Allowed doctors to see into the body to discover broken bones or damaged internal organs.

5. Marie Curie
Curie → discovered two radioactive elements, radium and polonium.
Also helped to discover how to find new elements.
Both elements she discovered are used in nuclear research.

6. Charles Darwin
Darwin → helped derive the theory of evolution; the idea that man developed from apes.
Posited that different organisms have to adapt over time to be able to survive and reproduce.
Those that manage to survive are considered to be naturally selected to survive due to their traits.
Broken into three parts: adaptation, competition, and natural selection

7. Gregor Mendel Mendel → helped discover the field of genetics.
Experimented with pea plants to figure out which traits are passed down and which ones are not.

8. Edward Jenner Jenner → introduced the practice of vaccination.
Figured out that if a patient is given a small amount of a virus, the patient will develop antibodies with which to fight the disease without contracting it.

9. Louis Pasteur
Pasteur → discovered how to remove bacteria from different liquids.
Discovered that heating materials will kill bacteria within it → pasteurization
Helped explain why immunization works.

10. Robert Koch Koch → helped discover how germs cause diseases.
Discovered what causes tuberculosis.
Developed a method of how to culture bacteria.

11. Joseph Lister and William Morton
- Lister → known for using antiseptics in hospitals.
- using Pasteur's knowledge about germs and their origins, Lister would use strong chemicals to kill bacteria in operating rooms.
- antiseptics, as they would later be called, prevented the spread of infection within hospitals.
- Morton → known for his experimentation with anesthetics.
- experimented with the use of ether as a means of dulling pain during surgery.
- the use of this anesthetic made it easier for patients to go through surgery and also speed up their recovery times.
