7906 Melanchton           Discovered 1960 Sept. 24 by C. J. van Houten and I. van Houten-Groeneveld on Palomar Schmidt plates taken by T. Gehrels.
Named after Philipp Melanchton (1497-1560), German reformer who worked closely with Martin Luther. At the early age of twelve, he took lectures at the University of Heidelberg. His personal synthesis of humanism and the Christian faith left a strong mark on German Protestantism, expressed in the Confessio Augustana in 1530.
