Huss (or Hus), Johann. Born probably in 1369. Bohemian reformer, attacked abuses in Prague University and among the clergy, and opposed German predominance. He was excommunicated by John XXIII for giving adhesion to Wycliffe's doctrines, and afterwards wrote his "Tractatus de Ecclesia." Having gone to the Council of Constance under a safe-conduct from the emperor, his enemies procured his imprisonment as a heretic and, on refusal to retract, he was burned to death in 1415.
