Nieuwl.

Reverend Julius Aloysius (Arthur) Nieuwland, CSC, Ph.D., (14 February 1878 – 11 June 1936) was a Belgian-born Holy Cross priest and professor of chemistry and botany at the University of Notre Dame. He is known for his contributions to acetylene research and its use as the basis for one type of synthetic rubber, which eventually led to the invention of neoprene by DuPont.

Nieuwland's parents emigrated from Hansbeke, Belgium in 1880 to South Bend, Indiana. As a young man, Nieuwland enrolled at the University of Notre Dame, where he studied Latin and Greek and received his undergraduate degree in 1899. He soon after began studies for the priesthood. Ordained in 1903, Nieuwland attended graduate school at The Catholic University of America, where he studied botany and chemistry. During his doctoral studies into the chemistry of acetylene, he discovered the chemical compound lewisite, which would later gain fame as a chemical warfare agent. Nieuwland had to be hospitalized for several days after his exposure to the newly synthesized compound; he did not purify it or otherwise pursue the matter any further.

After receiving his Ph.D. in 1904, Nieuwland returned to Notre Dame as professor of botany until 1918, and subsequently as professor of organic chemistry until 1936. In 1909, Nieuwland founded the peer-reviewed journal American Midland Naturalist acting as its editor until 1934. In 1920, he successfully polymerized acetylene into divinylacetylene. Elmer Bolton, the Director of Research at DuPont, used this basic research during the development of neoprene.
