Ambroise Paré (1510 1590)
At the beginning of the 16th century many surgical and medical treatments had
not changed for hundreds of years. The main method of stopping a wound
bleeding, for example, was to cauterise or seal it with a hot iron. Muslim doctors
had developed this technique 500 years earlier. The man who stumbled upon a
better by chance method was Ambroise Paré.
While on the battlefield, In an attempt to stop soldiers bleeding to death, wounds were
usually scorched with burning oil or a hot iron to seal them.
Paré had run out of oil in the battlefield so had to try an alternative method.
He made a dressing of egg whites, oil of roses and turpentine, which he applied to a wound.
The dressing successfully sealed the wound and provided relief from pain.

Andreas Vesalius (31 December 1514 15 October 1564)
Andreas Vesalius was a physician and anatomist. He is known for writing one of the most
influential books on human Anatomy, "De humani corporis fabrica."
Vesalius is known widely for being one of the first to question the famous anatomist

William Harvey (1 April 1578 3 June 1657)
William Harvey was an English physician who is widely known for being the
first person to describe in detail the systemic circulation and properties of
blood being pumped to the body by the heart.
Harvey attended the University of Padua just 50 years after Vesalius and, although Vesalius had

Harvey wanted that to stop. Harvey used carful calculations and experiments to realise that
Galen's theory on how blood circulated around the body was wrong. Galen believed that blood
was produced by the liver and then 'used up' by the body, Harvey proved that the amount of
plod pumped by the heart was so much that it couldn't be used up the way that Galen had
described. Harvey proved that the heart pumped blood around the body again and again, rather
than being "used up" like Galen had described.
Harvey was also the first to suggest that humans and other mammals reproduced via the
fertilisation of an egg by sperm.…read more
