Paraclesus Paracelsus (1493—1541) was a secretive alchemist about whom very little is known with certainty. He also contributed to the field of medicine, having been a notable physician. Paracelsus's bold theories challenged medieval thought. Paracelsus was credited with the discovery of Parseltongue. Paracelsus was a man born in 1493 in Austria. He was born Phillip Von Hohenheim, but changed his name to Philippus Theophrastus Aureolus Bombastus von Hohenheim, then to Paracelsus. He has made many contributions to medicine. He believed every human needed a balance of minerals and metals in their body and he was the first to use minerals and metals as medicine. Paracelsus also studied psychotherapy, and was the first to understand the subconscious.
