Nieuwland, Julius Arthur
Born: February 14, 1878, Hans Beke, Belgium
[Died] June 11, 1936, Washington, DC, USA
Belgian-born American chemist. After graduating from the University of Notre Dame, he studied at the Catholic University of America, receiving his doctorate in 1904. He was professor of botany (1904-18) and organic chemistry (18) at Notre Dame. His doctoral thesis was on the reactions of acetylene, but he continued his research and in 1928 succeeded in synthesizing an acetylene derivative using a mixture of cuprous chloride and ammonium chloride (Newland's catalyst). This discovery later led to the production of synthetic rubber (neoprene) by DuPont.
