French poet and dramatist who is credited with writing the first original French plays to observe the form of classical tragedies and comedies.

Before becoming a doctor of medicine at the University of Paris, Grévin wrote several successful comedies, including La Trésorière (performed 1559; “The Paymistress”). His comedies, licentious in tone, imitated the regular form of the Roman playwrights Plautus and Terence but took contemporary subjects and a Parisian setting. They were published in Grévin's Théâtre (1561), along with his La Mort de César, a tragedy on the Senecan model, for which he drew material from classical and contemporary sources. A friend and disciple of the poet Pierre de Ronsard, Grévin also wrote love sonnets and satirical sonnets.

Forced to flee France in 1560 because of his Protestant faith, Grévin took refuge at the Turin court of the Duchess of Savoy (Margaret of France), where he became her physician and counsellor and wrote medical treatises on antimony and poisons.
