Henri, Dauphin of Viennois

Henri de la Tour du Pin (1296–1328), also called Henri Dauphin, was the fourth son of Humbert I, Dauphin of Viennois, and Anne of Burgundy. Destined for the church but never ordained a priest, he became bishop of Passau in 1317 and was named bishop of Metz by Pope John XXII in 1319. From 1319 to 1323 he ruled the Dauphiné as regent for his nephew Guigues VIII.

His constant demands for money angered the people of Metz, and in 1325 he resigned his see, returned to lay life, and died in 1328.
