Antoni van Leeuwenhoek and other scienitist contribution to science 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.

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.
