For significant and continuing contributions in the field of superconducting materials, in particular:
for his pioneering work in developing high critical current density in niobium-titanium conductors
for his leadership in the commercialization, by a number of industrial companies, of multi-filamentary conductors of niobium-titanium and, later, of niobum-3-tin for many high energy physics accelerator projects, including the Superconducting Super Collider (SSC) and many fusion projects including the International Thermonuclear Experimental Reactor (ITER).
