Johannes Dryander

Johannes Dryander, also known as Johannes Eichmann, lived from 1500 to 1560 and is described as an academic. Born as Johannes Eichmann in Wetter in the Holy Roman Empire, he studied anatomy and medicine at the University of Paris and the University of Erfurt from 1528 to 1534 and then became professor of medicine at the University of Marburg in 1535. He held two public dissections in the following year and wrote the first text illustrating a Galenic dissection of the human brain in 1536, and his Anatomiae pars prior, an expanded edition of 1537, marked a significant transition from medieval scholasticism toward the precise observations of Andreas Vesalius. His books featured detailed illustrations of the brain, skull and cranial sutures, and he continued his work on astrology and mathematics until his death in 1560.
