9695 Johnheise           Discovered 1960 Sept. 24 by C. J. van Houten and I. van Houten-Groeneveld on Palomar Schmidt plates taken by T. Gehrels.
John Heise (b. 1942), professor of general physics at Utrecht University, specialized in high-energy space physics. In 1975 he discovered and detected sources of galactic x-ray bursts (1975). He was among the discoverers in 1998 of the origin of the cosmic \gamma -ray bursts. The name was suggested by C. de Jager.
