6659 Pietsch           Discovered 1992 Dec. 24 by T. Urata at Oohira.
Wolfgang Pietsch (b. 1948), at the Max-Planck-Institut für extraterrestrische Physik, started his career in the Astronomisches Institut Tübingen/MPE hard-x-ray group, building and analyzing balloon and space-based experiments that led to the detection of the cyclotron line in Her X-1 and hard x-ray emission from SN 1987A.
