Paracelsus (11 November or 17 December 1493 in Einsiedeln, Switzerland – 24 September 1541 in Salzburg, Austria) was a Swiss-Austrian alchemist, physician, astrologer, and general occultist. The name "Paracelsus" was a nickname: it means "equal to or greater than Celsus", and refers to his medical skill. He was born Phillip von Hohenheim.
He gained his doctorate degree from the University of Ferrara in 1515 or 1516.
