Gregory Hallock Smith is an optical engineer and lens designer. He first became interested in optics and astronomy in 1954 at age 13. In 1972, he received his Ph.D. from the Optical Sciences Center, University of Arizona. Since that time, he has held optical engineering positions at several major corporations and research institutions. His specialty is lens design. His experience ranges over such areas as photographic techniques, astronomical instruments, image intensifiers, optics for military and NASA spacecraft, and optics education.
