matthioli
Pietro Andrea Gregorio Mattioli was a 16th-century Italian physician, botanist and pharmacist.
Mattioli studied medicine in Padua and obtained a medical practice first in his hometown. Later, in the 1555-1560s, he served as personal physician to the imperial court of Ferdinand II, Archduke of Austria, and Emperor Maximilian II. This high position allowed him to test the effects of poisonous plants on prisoners for scientific purposes.
Mattioli published several scientific works in which he included many of his own observations on the flora of the Alps, including previously unexplored plants. These works, based on the study of books by predecessor scientists, gave impetus to the development of botany throughout Italy at the time. Mattioli kept up a lively correspondence with other researchers, describing specimens of rare plants received from them. The genus of flowering plants Matthiola is named after Mattioli.
