At DuPont, Carothers' work focused on polymerization and the ways in which polymers structurally analogous to cellulose and silk could be prepared. In early 1930, the chemists in Carothers' laboratory produced neoprene (synthetic rubber) and the first laboratory-synthesized fiber. In 1934, still working on polymerization theory, Carothers produced the first polyamide fiber which was later to become known as Nylon. During the next two years, Carothers suffered frequent bouts of depression. On April 29, 1937, three weeks after the basic Nylon patent application was filed, he committed suicide.
Johnson received his Ph.D. in chemistry from the University of Illinois, where he studied with Professor Roger Adams. At Illinois, Johnson became a close friend of Wallace Carothers, who in 1928 joined the Chemical Department of the DuPont Company, where he headed the Organic Chemistry Section that developed Nylon.
