4854 Edscott           Discovered 1981 Mar. 2 by S. J. Bus at Siding Spring in the course of the U.K. Schmidt-Caltech Asteroid Survey.
Edward Scott (b. 1947), professor at the University of Hawaii, began his career by deciphering how minor planet cores fractionally crystallized to produce the observed range of iron meteorite compositions. His current work focuses on the chemical and physical processes that operated in the solar nebula.
