George Oenslager

George Oenslager (September 25, 1873 – February 5, 1956)[1] was a Goodrich chemist who discovered that a derivative of aniline accelerated the vulcanization of rubber with sulfur.

In 1912, Oenslager was working with David Spence at Diamond Rubber on additives to improve the vulcanization process.

Working off of Oenslager's aniline additives, Spence discovered that p-aminodimethylaniline was a far superior accelerator, vastly improving the tensile strength of the rubber.

[citation needed] Oenslager received his Ph.D. from Harvard under Prof. Theodore William Richards.

[5] He was awarded the Perkin Medal in 1933 for his discovery of organic accelerators, specifically thiocarbanilide.
