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.
