12136 Martinryle           Discovered 1960 Sept. 24 by C. J. van Houten and I. van Houten-Groeneveld on Palomar Schmidt plates taken by T. Gehrels.
Martin Ryle (1918-1984) was a British astrophysicist who developed the aperture synthesis technique of interferometry and constructed large radio telescopes, using them to discover and catalogue numerous radio sources.
