1839 Charles Goodyear innovates the vulcanization of rubber. Soon after, he secures patents for condoms, douching syringes and cervical caps, but is unable to manufacture them, defend all his patents, or even make tires in his lifetime.
Charles Goodyear and the Vulcanization of Rubber - Obsessive dedication transformed rubber into a viable commercial material and made the town of Naugatuck one of its leading manufacturing sites in the 1800s. - See more at: http://connecticuthistory.org/charles-goodyear-and-the-vulcanization-of-rubber/
Hair comb, 1851 I. R. Comb Co., manufacturer; Charles Goodyear (American, 1800–1860), patentee Vulcanite Vulcanite was produced by treating natural or India rubber with sulfur, then exposing it to moderate heat. The resultant material was elastic enough to be fashioned into the desired shape while warm, but became hard and durable once cooled.

1839: American inventor Charles Goodyear (1800 - 1860) demonstrating his new dry heat rubber Vulcanization process. Goodyear found that adding sulphur to latex - the goopy sap of the rubber tree - created a much firmer, more durable material, which he used to produce the first tyres and inner tubes. The process was dubbed "vulcanisation" after Vulcan, the Roman god of fire (and volcanoes), and is still used to make rubber today.
