Julius Arthur Nieuwland

Died 11 Jun 1936 at age 58 (born 14 Feb 1878).Belgian-American organic chemist who studied reactions of acetylene and invented neoprene. He was ordained as a priest (1903) before earning his Ph.D. (1904). He did not pursue his own discovery of the reaction between acetylene and arsenic trichloride, but it led to the development of the chemical-warfare agent lewisite dubbed “the dew of death”, a poison gas and vesicant used in WW I. He collaborated with DuPont chemists in thepolymerization of acetylene and development of chloroprene, which in turn could be polymerized to the first really successful synthetic rubber, neoprene. This was superior to rubber in many ways such as in its resistance to sunlight, abrasion, and temperature extremes.
