Engraved portrait of Czech doctor of philosophy and medicine Ioannes Marcus Marci (also known as Joannes Marcus Marci, and as Jan Marek Marci), who taught over thirty years at Prague's Charles University. Marci was not only a personal physician to two emperors, but he studied epilepsy, the mechanics of colliding bodies, and the refraction of light. Credited as being one of the founders of spectroscopy, since 1977 the I. M. Marci Medal has been given annually for outstanding work in spectroscopy.
