Philippus Aureolus Theophrastus Bombastus von Hohenheim was a German-Swiss Renaissance physician, botanist, alchemist, astrologer, and general occultist. He founded the discipline of toxicology. He is also known as a revolutionary for using observations of nature, rather than looking to ancient texts, in open and radical defiance of medical practice of his day.He is also credited for giving zinc its name, calling it zincum, and for the terms „gas”, „chemistry”, and „alcohol”. Modern psychology often also credits him for being the first to note.
„Paracelsus”, meaning equal to or greater than Celsus, refers to the Roman encyclopedist Aulus Cornelius Celsus from the 1st century, known for his tract on medicine.
