Charles Goodyear - The History of Vulcanized Rubber

Caoutchouc was the name for rubber used by the Indians of Central and South America. History of Caoutchouc Besides pencil erasers, rubber was used for many other products, however, the products were not standing up to extreme temperatures, becoming brittle in winter. During the 1830s, many inventors tried to develop a rubber product that could last year-round. Charles Goodyear was one of those inventors, whose experiments put Goodyear into debt and involved in several patent lawsuits.

This process called vulcanization made rubber waterproof and winter-proof and opened the door for an enormous market for rubber goods.
