Ira Williams (1894–1977[1]) was an American chemist at DuPont's Jackson Laboratory in New Jersey, who in the summer of 1930,[2] together with Wallace Carothers, Arnold Collins and F. B. Downing, made commercial Neoprene possible[3] by producing a soft, plastic form of chloroprene that could be processed by the rubber industry.[4][5] Early accounts of the development credited Julius Nieuwland with synthesizing the precursor divinylacetylene.[6] Williams' contribution was the discovery that the rheological behavior of the product could be controlled by quenching the polymerization reaction with alcohol.
He won the 1946 Charles Goodyear Medal.
