Believed that God and the Devil influenced health.
Disease was seen as God’s punishment for sins
Astrology became important. Doctors studied star charts
because they believed that the movement of the planets
affected people’s health.
Doctors followed the ideas of Galen. They
believed illness was caused by an imbalance in
humours.
Vesalius
Did his own dissections and wrote books
based on his observations using accurate
diagrams to illustrate his work. His most
famous book was ‘On The Fabric of the
Human Body’ written in 1543.
Vesalius encouraged doctors to
dissect and look for themselves
He was able to point out some of Galen’s mistakes. Vesalius said
there were no holes in the septum of the heart and that the jaw
bone is not made up of two bones.
William Harvey
Discovers the circulation of the blood,
disproving Galen’s ideas.
Blood groups are discovered in 1901, which makes blood
transfusions successful.
Identifies the difference between arteries and veins.
To spread his ideas he writes “An Anatomical Account
of the Motion of the Heart and Blood”. However,
bleeding operations still continue after Harvey as
people are unsure of what else to d
The Black Death – 1348
Spread by coughs and sneezes or by black rat flea bites – black rats were
carried overseas by ships. Arrived in Britain in 1348. Its victims were struck
down suddenly and most died.
Symptoms included exhaustion, high temperatures,
swellings and difficulty breathing.
Ships were made to wait 40 days before landing –
they were quarantined.
Edward Jenner
Jenner was a country doctor. He heard that
milkmaids didn’t get smallpox, but instead a
milder cowpox.
Jenner investigated and discovered people who had
already had cowpox didn’t get smallpox.
In 1796 he took a small boy and injected him with
pus from the sores of a milkmaid with cowpox.
Jenner then injected James with smallpox. James
didn’t catch the disease!
Germ theory 1857
Louis Pasteur was employed in 1857 to find the explanation for the souring of sugar beet used in
fermenting industrial alcohol. His answer was to blame germs in the air
He proved there are germs in the air by sterilising water
and keeping it in a flask that didn’t allow airborne particles
to enter. This stayed sterile – but sterilised water kept in an
open flask bred microbes again.

1848 Public Health Act
Annotations:
The government did nothing at first about Chadwick’s recommendations.
However, in 1848 there was another outbreak of cholera, this put pressure on the government to do
something. Parliament reluctantly agreed to pass Public Health Act.
Although it was not compulsory. The government set up a Board of Health to encourage, but not to force,
local authorities to improve conditions.
They gave local authorities money to make improvements in their areas if they wanted to and had the
support of local ratepayers.
Only a few local authorities took any new measures.
By 1872 only 50 Medical Officers of Health had been appointed.
The Board of Health was abandoned in 1854.
1867 Second Reform Act
Annotations:
Working class men were given the right to vote.
For the first time, it wasn’t just the ratepayers who got a say in improving public health.
MPs were forced to improve the living conditions of the poor.
1875 Second Public Health Act
Annotations:
Unlike the 1848 Public Health Act, the 1975 Public Health Act actually forced local authorities to introduce the
following measures:
Provision of clean water
Proper drainage and sewage
The appointment of a Medical Officer of Health
1853 John Snow
Annotations:
In 1854 John Snow proved that there was a link between cholera and water supply. He used research,
observation and door-to-door interviews to build a detailed map of a cholera epidemic in Broad Street.
Nearly all the deaths had taken place within a short distance of the water pump.
Near to the pump, there was a brewery and none of the people there had cholera. The brewery had its
own water pump, and the men had been given free beer. They didn’t use the Broad Street Pump at all.
After collecting evidence, John Snow removed the handle from the Broad Street pump.
There were no more deaths. It later came to light that a cesspool near to the pump had a cracked lining
which allowed the contents to contaminate the drinking water.
Snow put pressure on water companies to clean up their water supplies.
