Jean Allarmet Brogni, cardinal de, a Roman prelate, born at Brogni, Savoy, in 1342, died in Rome, Feb. 16, 1426. He was a swineherd in his youth, and was successively made bishop of Viviers and of Ostia, archbishop of Aries, and bishop of Geneva, and finally cardinal and chancellor of the church of Rome. During the great schism which divided the church for more than 40 years, Brogni devoted himself to the work of conciliation. The council of Constance being called for that purpose by John XXIII. and the emperor Sigis-mund, the former was deposed at the sixth session, after which Brogni presided as senior cardinal until the 41st, when Cardinal Colonna was elected pope, Nov. 14, 1417, chiefly through Brogni's influence, under the name of Martin V., and the holy see was once more established at Rome. As president of the council he had to pronounce the sentence of death upon Huss, to whom he had shown great kindness during the trial. The cardinal was the founder of the hospital of Annecy, of the college of St. Nicholas at Avignon, and other charitable institutions.
