Gregor Horst

Gregor Horst Latinized as Gregorius Horstius was a German physician, anatomist and professor of medicine at the University of Giessen. He promoted a shift from regurgitation of old medical ideas and was called Practicus prudens and "the Aesculapius of the Germans". He tried to establish a rational approach to medicine and his motto ratione et experientia was included in his portraits.
