Petrus Borel
1620 - 1671
Pierre Borel (Latin: Petrus Borellius; c. 1620 – 1671)[1] was a French savant: a chemist (and reputed alchemist), physician, and botanist.
He concerned himself with an eclectic range of subjects: optics, ancient history, philology and bibliography. His biographers have tended to deplore his spreading of himself over so many areas.
Borel was the first to apply microscopy to medicine.
