Philip Melanchthon
Philip Melanchthon (born Philipp Schwartzerdt; 16 February 1497 – 19 April 1560) was a German Lutheran reformer, collaborator with Martin Luther, the first systematic theologian of the Protestant Reformation, intellectual leader of the Lutheran Reformation, and an influential designer of educational systems. He stands next to Luther and John Calvin as a reformer, theologian, and molder of Protestantism. After Luther himself, he is the primary founder of Lutheranism.
Herluf Trolle
At the age of nineteen, Trolle went to Metropolitanskolen ("Vor Frue Skole") at Copenhagen, subsequently completing his studies at Wittenberg University from 1536-1537. Here he adopted the views of the German Lutheran reformer Philipp Melanchthon (1497–1560), with whom he was in intimate correspondence for some years.
