Guillaume Court

Guillaume Court (c. 1290–1361), born at Belpech, was a Cistercian theologian who received a doctorate in theology in 1319. He aided his uncle, the inquisitor Jacques Fournier, in the heresy trials at Montaillou.

When Fournier became Benedict XII, he made Court Bishop of Nîmes in 1337 and raised him to cardinal in 1338. Called the white cardinal, probably for the Cistercian robe he wore, he sat in the conclaves of 1342 and 1352 and served as legate in Lombardy.

In 1354 he headed the Avignon tribunal that cleared Joannes de Rupescissa, ordered to write the Book of Secret Events; two others were condemned and burned. He died at Avignon on 12 June 1361.
