“ HALLER, BERTHOLD (1492–1536) , Swiss reformer, was born at Aldingen in Württemberg, and after studying at Pforzheim, where he met Melanchthon, and at Cologne, taught in the gymnasium at Bern. He was appointed assistant preacher at the church of St Vincent in 1515 and people’s priest in 1520. Even before his acquaintance with Zwingli in 1521 he had begun to preach the Reformation, his sympathetic character and his eloquence making him a great force. ”
