Philip Melanchthon
He was born Philipp Schwartzerdt on 16 February 1497, at Bretten where his father Georg Schwarzerdt was armorer to Philip, Count Palatine of the Rhine. His birthplace, along with almost the whole city of Bretten, was burned in 1689 by French troops during the War of the Palatinate Succession. The town's Melanchthonhaus was built on its site in 1897.

Borrhaus was born in Stuttgart and raised as an adopted child of a Simon Keller. He enrolled at the University of Tübingen, where in 1515 he graduated and came to know Philipp Melanchthon. In 1520, he moved to the University of Ingolstadt, where he took up the study of Greek and Hebrew, and theology under Johann Eck. Following a dispute with Eck, he left for Wittenberg, where he taught mathematics at the private school of Melanchthon. However his ideas became more radical, and he was expelled for heterodoxy in April 1522. Borrhaus travelled in the company of Felix Manz through Switzerland, Austria, Poland and Prussia. In 1526 he moved to Strasbourg, where he married Odilia of Utenheim. Under the influence of Wolfgang Capito, Borrhaus published his first work, "De operibus Dei" 1527. In 1536 his wife died and Borrhaus went to Basel, where he earned a living as a glass blower and married again. In 1541 his friend Simon Grynaeus arranged for Borrhaus a position teaching philosophy at the University of Basel, and then in 1544 he became professor of Old Testament and 1546, 1553 and 1564 served as rector. He died in Basel.
