19366 Sudingqiang           Discovered 1997 Nov. 6 by the Beijing Schmidt CCD Asteroid Program at Xinglong.
Su Ding-qiang (b. 1936), an astronomer and optical engineering expert, made many creative contributions to Chinese astronomical instruments, including a new idea to apply active optics to obtain the shape of a changeable optical system that could not be realized in the conventional way.
