Bertrand de La Tour

Bertrand de La Tour, also known as Bertrand de Turre, was a French Franciscan theologian and cardinal.
Bertrand was born in Camboulit in the old province of Quercy, France. Serving as a provincial minister in Aquitaine from 1312 onwards he became a leading opponent of the Franciscan Spirituals. He undertook diplomatic missions for Pope John XXII with Bernard Gui from 1317–1318. After this time, he was asked to aid in evaluating the heresy of Peter Olivi. Bertrand was made Archbishop of Salerno and then Cardinal of San Vitale in 1320. In 1323 Bertrand was appointed cardinal bishop of Tusculum.
After the deposition of Michael of Cesena in 1328, on John XXII's behest Bertrand acted as vicar general of the Franciscan Order.
He was nicknamed "Doctor famosus".
