8237 Constable           Discovered 1960 Oct. 17 by C. J. van Houten and I. van Houten-Groeneveld on Palomar Schmidt plates taken by T. Gehrels.
Named for the English painter John Constable (1776-1837), known for his landscapes painted directly from nature. A forerunner of the Impressionists of the late nineteenth century, he is notable for his use of color. For some time he made portraits, but later he went back to landscape painting.
