Robert Hooke
Robert Hooke: (1635-1703) Hooke was a scientist during the 17th century and and contributed to this great scientific time. In 1665 he wrote a book called Micrographia and it was about life cycles and how stuff became what it was. But he also drew many things through his microscope and they were very good. Using his microscope he hiped discover cells without even realizing it! -
Anton van Leewenhoek
Anton van Leeuwenhoek: (1632-17230 Anton was very good at building microscopes and this got him very interested in microscopic life. With his microscope he observed small life moving around in water and then later say more small things he called animalcules in his teeth. He was one of the first people to see microbes ever around 1673. -
Matthias Kakob Schleiden
Matthias Jakob Schleiden: (1804-1881) Matthias liked to use microscopes to look at and study plants. And by doing this, in 1838, he found out or suggested that all plants are made up of cells. He is partialy credited with the cell theory. -
Theodor Schwann
Theodor Schwann: (1810-18820 Much like Matthias he liked to study things using microscopes also but instead he studied animals. And in 1839, he too found out that animals were made up of cells. Because of this he is partially credited with the cell theory. -
Ignaz Philipp Semmelweis
Ignaz Philipp Semmelweis: (1818-1865) It was in the 1840s when he said that childbed fever was infectious and could be spread from person to person. By simply washing his hands his patient death rates dropped 11%. So he concluded that hand washing reduced the risk of infectious disease by removing germs that can kill people. -
Karl Theodor Ernst von Siebold
Karl Theodor Ernst von Siebold: (1804-1885) In 1845 Karl continued Schwann's and Schleiden's ideas by saying that microbes were too made up of cells. And he was right by stating microbes were living and were the same as animals and plants! -
Rudolf Carl Virchow
Rudolf Carl Virchow: (1821-1902) He is well known for stating that “all cells arise from cells,”some where in the 1850's. And he was right, he found the multicellular organisms. He then stated that diseases and sicknesses come from unhealthy cells. He also stated that all living organisms start out as single as a single cell. Which is completely true! -
Florence Nightingale
Florence Nightingale: (1820-1910) In 1860 she published her thoughts on diseases. She is credited as one of the first people to realize that cleanliness is a good practice. These ideas helped improve military hospitals and and led to fewer deaths. -
Louis Pastuer:
Louis Pastuer: (1822-1895) He began to study microbes in 1864. In his fermentation job he discovered that some microbes could cause food to spoil and in the end get people sick. So he discovered that heat can kill these microbes and that process is now known as Pasteurization. He also said that microbes could spread diseases and called them germs, the basis of the germ theory of disease. -
Joseph Lister
Joseph Lister: (1827-19120) In 1867 he started to use antiseptics to clean surgical tools. He washed his hand and sprayed aprons and clothes and because of this his patient death rate dropped 15%! -
Robert Koch
Robert Koch: (1843-1910) In 1876 Koch discovered the microbe that causes anthrax. And he also identified the microbes that caused tuberculosis and cholera. Robert also developed Agar which is a jello like material that is used to grow microbe cultures. And it is still used to this day! -
William Stewart Halsted
William Stewart Halsted: (1852-1922) In 1890 he came up with the idea of trying to prevent the spread of germs rather than killing them. So he was the first person ever to use rubber gloves in surgery! His glove cam heated and sterilized which helped prevent these germs. -
The Germ Theory of Diesase
The germ theory of disease has now become a proven and a well trusted idea in 1931!
