Wallace Hume Carothers and the discovery of nylon
Wallace Hume Carothers is an American chemist and inventor, he worked at the DuPon't's research facility at the DuPont Experimental Station near Wilmington Delaware ( where most of the polymer research was done ) as the group leader. Carothers worked in many universities before he was hired by Dupont to work on fundamental research. On the 28 February 1935 he discovered the way on making nylon so it can replace silk. Nylon became famous when it was introduced as a fabric at the 1939 New York World's Fair. Nylon is not a natural material such as wood and iron etc, it is made by reacting together two large molecules using heat and pressure in the autoclave to form repeating links.
