Johann Dryander (1500 - 1560)

Johann Dryander

Johann Dryander, born Johann Eichmann, was a German medical anatomist, mathematician and astrologer.

He studied anatomy and medicine at the University of Paris and the University of Erfurt, and in 1535 became professor of medicine at the University of Marburg. A year later, Dryander performed two public autopsies, making the first illustrated description of the dissection of the human brain. Dryander titled his book Anatomiae, hoc est, corporis humani dissectionis pars prior ("Anatomy, that is, the dissection of the human body, part one," suggesting a sequel, which, however, did not follow.

His work made a significant contribution to the development of modern anatomy. Toward the end of his life, Dryander also dabbled in astrology and mathematics.
