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, fightiJohn 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.
