Walter Reed's Life Span Walter Reed worked in the U.S Army as a Physician. He worked in and around the subject area of Yellow Fever. In 1901 he led the team which confirmed Carlos Finlay's theory that Yellow Fever is actually transmitted through a certain species of mosquitos rather than through direct contact. This insight led to the enhancement of the fields of Microbiology and Epidemiology. The insight also led to the almost immediate completion of the Panama Canal.
Edward Jenner's Life Span Edward Jenner is usually named as the "Pioneer of Immunization." Jenner noticed from observation, that the milkmaids were generally immune to smallpox. He theorized that the the pus in the blisters that milkmaids recieved from cowpox, protected them from smallpox. He tested his theory by exposing James Phipps to a small dosage of cowpox and then Smallpox. James showed no symptoms.
Alexander Fleming's Life Span Alexander Fleming discovered Penicillin. A drug which has the ability to fight of certain bacterias. He did this, completely by accident. He was experimenting in the creation of bacteria in petri dishes before he left for holiday with his family. Being a very messy man he didn't clean up his lab. When he returned, the bacteria had formed a ring of mould around it. After close observation, experimentation and recreation, he noticed the wonders this mould could perform, fighti
John Snow's Life Span John Snow is considered to be the one of the founders of modern microbiology. This is mainly due to his work in tracing the source of the Cholera outbreak in London. He mapped out cases of Cholera and determined that the cases were mainly around the water pumps, where citizens would go to get water. He observed that the water companies were taking the water through sewage areas, before taking it to the pumps. His work led to an improvement in waste systems around the world.
Louis Pasteur's Life Span Louis Pasteur is most famous for the invention of the technique pasteurization, named after him. Pasteurization is a process where a mixture of water and certain foods, such as milk, are treated with mild heat, to eliminate pathogens and extend shelf-life. Today, pasteurization is critical in the food industry in order to ensure food safety.
