Wallace Hume Carothers

Died 29 Apr 1937 at age 41 (born 27 Apr 1896). American chemist who developed nylon (1935), the first synthetic polymer fibre to be spun from a melt. He produced this polyamide, by condensation of adipic acid and hexamethylenediamine. He worked for the duPont chemical company as head of organic chemistry research from 1928. Through his study of long-chain molecules, now called polymers, he also developed the first successful synthetic rubber, neoprene (1931). He suffered from depression, and died by suicide at the age of 41 before nylon had been commercially exploited. DuPont produced nylon commercially from 1938 and laid the foundation of the synthetic-fibre industry. Nylon proved outstanding in its properties as a synthetic analog of silk.
