3635 Kreutz           Discovered 1981 Nov. 21 by L. Kohoutek at Calar Alto.
Heinrich Carl Friedrich Kreutz (1854-1907), astronomer at the Kiel Observatory and from 1896 editor of the Astronomische Nachrichten, is renowned for his seminal three-part study of the family of bright sungrazing comets, now known as the Kreutz Group. The name was suggested by M. Meyer, R. Kracht and B. G. Marsden.
