PIERRE Guerin De TENCIN (1679-1758), French ecclesiastic, archbishop of Embrun and Lyons, and cardinal, was born at Grenoble on the 22nd of August 1679. He owed his quick advance to power to his sister Claudine (see above). He was a strong opponent of the Jansenists, and in 1742 was appointed a minister of state to Louis XV., though he held no portfolio. He died on the 2nd of March 1758.
