Born: July 5, 1487, Neustadt an der Aisch, Franconia.
Died: April 29, 1541, Königsberg, Prussia (now Kaliningrad, Russia).
Graumann studied at Leipzig (MA 1516, BD 1520), and in 1520 was appointed rector of the St. Thomas School in Leipzig.
He attended the Disputation in 1519 between Dr. Eck, Luther, and Carlstadt, as the amanuensis of Eck. The ultimate result was that he supported the Reformation, and left Leipzig in 1522.
In 1523, he became Evangelical preacher at Würzburg, but left at the outbreak of the Peasants’ War in 1525.
He went to Nuremberg, where, around Lent, he was appointed preacher to the nunnery of St. Clara. Then, at the recommendation of Luther, he received from the Margrave Albrecht of Brandenburg, an invitation to help further the Reformation in Prussia.
He began his work as pastor of the Altstadt Church in Königsberg in October 1525. There he was well known for his work in organizing the evangelical schools in the province.
