Who was Andreas Vesalius.
Andreas Vesalius was a Renaissance physician.
He is known primarily as this, who refuted the theories of the great ancient medic Galen. He managed to do so thanks to his extraordinary courage. During studies, when he suspected that his famous predecessor might be wrong about the structure of the human body, He risked his own life and decided to dig up the body. This allowed him to convince himself, that part of Galen's theory is wrong.
Already at age 24 years he became a professor of anatomy. Thus, he gained the privilege of working with students. This enabled him to introduce an innovative teaching method. He went down to the students, where they performed an autopsy together. He asked them for it, that they accurately describe what they see and compare it with the knowledge given to them by Galen. At the same time, he conducted his own observations and prepared drawings. At the time, when he felt the support of his students, he decided to publish the work, to refute the teaching of Galen. There was a year 1538. As it is not difficult to guess, the new theories have caused quite a stir. The next year brought a new work, which openly criticizes old science. W 1543 Vesalius decided to publish a volume of his own anatomy, Humani Corporis Fabrica. In it he proves Galen's errors in 200 places. Unfortunately, it was not widely accepted, which led to the sending of a doctor on a forced pilgrimage to the Holy Land, during which he dies. His teaching does not, however, which is continued by the disciples of Vesalius.
