Name Contribution
Antoni Leeuwenhoek Consider him to be the father of Microbiology. Began making and using simple microscope.
Examined water and visualized tiny animals, fungi, algae and single celled protozoa (animalcules).
Viruses however were too small to be seen.
By the end of the 19th century these organisms were called microorganisms.
Leeuwenhoek’s microorganisms can be grouped into six cate- gories:
▪ Bacteria
▪ Achaea
▪ Fungi
▪ Protozoa
▪ Algae
▪ Small multicellular animals
Carolus Linnaeus Developed a taxonomic system for naming plants and animals and grouping similar organism together.
Robert Koch Studied causative agents of disease Developed Koch’s Postulates
• suspected causative agents must be found in every case of the disease and be absent from health hosts
• agent must be isolated and grown outside the host
• when agent is introduced into a healthy, susceptible host, the host must get the disease
• same agent must be found in the diseased experimental host
Alexander Fleming Discovered Penicillin
He discovered an enzyme, lysozyme
Louis Pasteur He developed the germ theory of disease Began work on fermentation
Pasteur conducted a series of experiments that addressed the cause of fermentation.
Led to the development of pasteurization
Process of heating liquids just enough to kill most bacteria Intentional use of microbes for manufacturing products Pasteurization (Apply high heat for a short period of times Kills most organisms not all)
Ignaz Semmilweis Required medical students to wash their hands in chlorinated lime water which resulted in higher patient’s survival rates
Joseph Lister Invented Listerine
Advanced antisepsis in health care setting.
Sprayed wounds, surgical incisions and dressings with carbolic acid (phenol)
Florence Nightingale Introduced cleanliness and antiseptic technique into nursing [Show Less]
