HISTORY OF MEDICINE FIGHTING DISEASE
Jenner & Inoculation
People attempted to infect themselves by catching smallpox of somebody
who had a mild form of it. The hoped that they would become immune to it.
Through observation he discovered the local belief that milkmaids who had
caught cowpox never caught smallpox. In 1796 he tested this theory on a
young boy, James Phipps, by infecting him with cowpox and then with
smallpox to find that he survived. Jenner called this process vaccination.
There was mixed reaction to his discovery. Many doctors didn't approve as
they were happy using the old method of inoculation which made them rich
and nobody could explain how the vaccine worked. However members of
the royal family had the vaccine and its success encouraged its use to be
In 1840 the vaccine was made free for all infants and in 1853, it was made
compulsory the first time the government had interfered with the health of
Louis Pasteur & Germ Theory
Thanks to advances in microscopes by the 19th Century most scientists knew
of the presence of germs or microbes, but thought them to be a result of
disease not a cause. Theory of Spontaneous Generation.
Pasteur did not set out to find the cause of disease but to solve problems for
businesses. He examined how sugar beet went sour during fermentation and
By an experiment using a swan-neck flask, he proved there to be a link
between germs and decay by conducting this experiment in public.
In 1865 he studied a silkworm disease, pebrine and in 1867 he proved germs
caused pebrine and found the link between germs and disease.
Koch began where Pasteur left of, by trying to link a particular microbe to a
particular disease, using his detailed medical knowledge that Pasteur lacked.
He discovered the anthrax microbe in 1875, TB in 1882 and cholera in 1883.
He used developments in bacteriology to stain normally invisible dyes
(taking advantage of the successful German dye industry) and then placed a
new kind of lens in his microscope to photograph and prove his findings.
He also developed a solid culture which were more reliable that Pasteur's
Together with Pasteur discovering the cause of disease and Koch
discovering the specific microbes responsible, the path was opened to
control disease and develop vaccines.
