11740 Georgesmith           Discovered 1998 Oct. 22 by the OCA-DLR Asteroid Survey at Caussols.
George Smith (b. 1930) co-invented the CCD while at Bell Laboratories in 1969. This device has revolutionized both amateur and professional astronomy. This minor planet was automatically detected by a CCD during a professional survey.
