Gregor Horst

Gregor Horst Latinized as Gregorius Horstius (5 November 1578 – 9 August 1636) 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 as Practicus prudens (experienced practitioner) and as the Aesculapius of the Germans. He tried to establish a rational approach to medicine and his motto ratione et experientia (reason and experience) was included in his portraits.
