Paracelsus (born Phillippus Aureolus Theophrastus Bombastus von Hohenheim, 1493-1541) was a Renaissance physician, botanist, alchemist, astrologer, and general occultist. "Paracelsus", meaning "equal to or greater than Celsus", refers to the Roman encyclopedist Aulus Cornelius Celsus from the first century known for his tract on medicine. He is also credited for giving zinc its name, calling it zincum, and is regarded as the first systematic botanist.
Self-proclaimed alchemist Phillip Theophrastus Gribbleflotz claimed that he was a great grandson of Paracelsus. However, Gribbleflotz lacked any skill and knowledge, and was considered a charlatan. He is believed to be using his supposed descent from with Paracelsus to boost his credibility.
Gribbleflotz, while working, later discovered his "great grandfather's" notes on zinc and renamed it zinken as a way to "honor" Paracelsus.
