First Do No Harm

Paracelsus, pseudonym of Philippus Aureolus Theophrastus Bombastus von Hohenheim, (Einsiedeln, December 17, 1493 – Salzburg, September 24, 1541) was a Swiss-German physician, alchemist, physicist, astrologer, and occultist. He is also credited with creating the name of the element zinc, calling it... zincum.
His pseudonym means "superior to Celsus (Roman physician)". In the study of his biography, fact has been gradually separated from belief, but no agreement has been reached regarding the nature and meaning of his teaching. He is considered by many to be a reformer of medicine. He is also acclaimed for his achievements in Chemistry and as the founder of Biochemistry and Toxicology.
He appears among scientists and reformers such as Andreas Vesalius, Nicolaus Copernicus, and Georgius Agricola, and is therefore seen as a modern figure. On the other hand, he has always possessed an aura of mysticism and even the obscure reputation of a magician.
