Johannes Dryander

Johannes Dryander, born Johannes Eichmann (1500 to 1560), was a German anatomist and professor of medicine. Born in Wetter, he studied anatomy and medicine at the University of Paris and the University of Erfurt between 1528 and 1534, and in 1535 became professor of medicine at the University of Marburg. He held two public dissections in 1536 and in that year published the first text to illustrate a Galenic dissection of the human brain. His Anatomiae pars prior of 1537, an expanded edition, marks a transition from medieval scholasticism toward the precise observation of Vesalius, with detailed illustrations of the brain, the skull and the cranial sutures drawn from his own dissections. His 1542 translation of the anatomy of Mundinus angered Vesalius because it plagiarised part of the Tabulae sex. He continued to work on astrology and mathematics until his death in 1560, and his early books contributed to the development of modern anatomy.
