The DuPont company’s organic chemist Wallace Carothers received a patent for linear condensation polymers, the basis of the material better known as nylon.
Carothers joined DuPont from Harvard University, where he had taught organic chemistry. He was initially reluctant to move due to concerns that his history of depression would be a problem in an industrial setting, but DuPont executive Hamilton Bradshaw persuaded him otherwise and he took up his role in February 1928.
Having thrown himself into researching the structure and synthesis of polymers, Carothers and his team were responsible for creating the first synthetic replacement for rubber which was later named neoprene. Their laboratory, which was nicknamed “Purity Hall”, then began to focus on producing synthetic fibres that could be used in place of silk as this was becoming harder to source due to declining relations with Japan following the Great Depression.
