"Berchtold Haller (c. 1492 – 25 February 1536) was a German Protestant reformer. He was the reformer of the city of Bern, Switzerland, where the Reformation received little to none opposition.
Haller was born at Aldingen in Württemberg. After schooling in Pforzheim, where he established a friendship with Philipp Melanchthon, he studied theology in Cologne. He became a teacher in Rottweil in 1510 and in Bern in 1513, where he was appointed assistant preacher at the church of St Vincent in 1515. In 1520 he became a canon and the people’s priest.
Even before his acquaintance with Huldrych Zwingli in 1521 he had begun to preach the Reformation, his sympathetic character and his eloquence making him and the painter and writer Niklaus Manuel a great force. Zwingli became his friend and adviser and they began a lively exchange of letters." - (en.wikipedia.org 31.01.2020)
