(8527) Katayama Main-belt Asteroid
Discovered on 28 September 1992 by Endate, K., Watanabe, K. at Kitami.
Using unparalleled techniques in electron microscopy, Japanese biophysicist Eisaku Katayama (b. 1949) revealed molecular shapes of various proteins in their functional states with a resolution that can only be superseded by x-ray study. He also contributed to new techniques in astronomical photography.Naming citation (20000320/MPCPages.arc), IAU / Minor Planet Center, via NASA/JPL
