Valentin Friedland (February 14, 1490 – April 26, 1556), also called Valentin Troitschendorf (or Trozendorf or Trotzendorf or Trocedorfius) after his birthplace, was an eminent German scholar and educationist of the Reformation. Friedland was a friend of Martin Luther and Melanchthon. His fame as a teacher was an attraction of Goldberg in Silesia, where he taught pupils from far and near. The secret of his success lay in his inculcating on his pupils respect for their own honour. He had a great faith in the intelligence that evinced itself in clear expression.
Friedland was born in Trozendorf near the town of Görlitz in Upper Lusatia, of parents so poor that they could not keep him at school. The boy taught himself to read and write while herding cattle; he made paper from birch bark and ink from soot. When difficulties were overcome and he was sent for education to Görlitz, his mother's last words were "Stick to the school, dear son". The words determined his career: he refused all ecclesiastical promotion, and lived and died a schoolmaster.
Friedland became a distinguished student at the University of Leipzig, learned Ciceronian Latin from Peter Mosellanus and Greek from Richard Croke, and after graduation was appointed assistant master in the school at Görlitz in 1515. There he also taught the rector and other teachers. When Martin Luther began his attack on indulgences, Trotzendorff resigned his position and went to study under Luther and Melanchthon at Wittenberg, supporting himself by private tuition. Thence he was called to be a master in the school at Goldberg, and in 1524 became rector. There he remained three years, when he was sent to Liegnitz.
