At the time, he was using carbolic acid, which we don't use anymore today. However, our care to keep surgical patients free from sepsis came from his work. https://padlet.com/valeriebblanchette/jj4g0tksb89okcgx/wish/2288350544 2022-09-08 14:59:15 UTC https://padlet.com/valeriebblanchette/jj4g0tksb89okcgx/wish/2288350544 1590: Zaccharias and Hans Janssen https://padlet.com/valeriebblanchette/jj4g0tksb89okcgx/wish/2291387270 In 1590, Zaccharias and Hans Janssen discovered that optical images can be viewed and enlarged using different kind of lenses. Then later developed the first compound microscope that consists of simple tube with lenses at each end. The magnification only ranged from x3 to x9. ]]> 2022-09-11 20:09:02 UTC https://padlet.com/valeriebblanchette/jj4g0tksb89okcgx/wish/2291387270 1546: Girolamo Francastro, an Italian physician, poet, astronomer, and geologist suggested that invisible organisms may cause diseases. https://padlet.com/valeriebblanchette/jj4g0tksb89okcgx/wish/2291447707 2022-09-11 22:16:21 UTC https://padlet.com/valeriebblanchette/jj4g0tksb89okcgx/wish/2291447707 1655: Robert Hooke was the first to visualize microorganisms and he later published "Micrographia" in 1665, a book in which he describes his observations made through a microscope. https://padlet.com/valeriebblanchette/jj4g0tksb89okcgx/wish/2291458423 2022-09-11 22:32:29 UTC https://padlet.com/valeriebblanchette/jj4g0tksb89okcgx/wish/2291458423 1898: Martinus Beijerinck, a Dutch microbiologist and botanist, discovered viruses and he was one of the founders of virology and environmental microbiology. https://padlet.com/valeriebblanchette/jj4g0tksb89okcgx/wish/2291467829 2022-09-11 22:48:26 UTC https://padlet.com/valeriebblanchette/jj4g0tksb89okcgx/wish/2291467829 Anton van Leeuwenhoek (October 24, 1632–August 30, 1723) invented the first practical microscopes and used them to become the first person to see and describe bacteria, among other microscopic discoveries. Indeed, van Leeuwenhoek's work effectively refuted the doctrine of spontaneous generation, the theory that living organisms could spontaneously emerge from nonliving matter. His studies also led to the development of the sciences of bacteriology and protozoology. https://padlet.com/valeriebblanchette/jj4g0tksb89okcgx/wish/2291520940 2022-09-12 00:28:13 UTC https://padlet.com/valeriebblanchette/jj4g0tksb89okcgx/wish/2291520940 1831: Robert Brown https://padlet.com/valeriebblanchette/jj4g0tksb89okcgx/wish/2292492957 In 1831, while investigating the fertilization mechanisms of plants in the Orchidaceous and Asclepiadaceous families, he noted the existence of a structure within the cells of orchids, as well as many other plants, that he termed the "nucleus" of the cell.]]> 2022-09-12 14:38:52 UTC https://padlet.com/valeriebblanchette/jj4g0tksb89okcgx/wish/2292492957
