7146 Konradin           Discovered 1960 Sept. 24 by C. J. van Houten and I. van Houten-Groeneveld on Palomar Schmidt plates taken by T. Gehrels.
Named in honor of Konradin Ferrari d´Occhieppo (b. 1907), professor emeritus of astronomy of Vienna University and full member of the Austrian Academy of Sciences, on his forthcoming ninetieth birthday. Well known in Austria as a profound teacher and scientist, he is also a nobleman of extraordinary personal modesty and generosity. He has worked on variable stars, as well as on astrometric and calendrical problems and the history of astronomy. His main interest has been in the astronomical aspects of the Star of Bethlehem, a subject to which he devoted a book and many articles. Name suggested by H. F. Haupt (who prepared the citation) and L. D. Schmadel.
