After a long period attempting to develop a process to upgrade rubber qualities (such as including nitric acid) that almost ruined him, in 1840 Goodyear discovered vulcanization, quite by accident. An interesting fact: in 1815, a humble sawyer-Hancock-became one of the leading manufacturers in the UK.
Condoms have been made from a variety of materials; prior to the 19th century, chemically treated linen and animal tissue (intestine or bladder) are the best documented varieties. Rubber condoms gained popularity in the mid-19th century, and in the early 20th century major advances were made in manufacturing techniques.Prior to the introduction of the combined oral contraceptive pill, condoms were the most popular birth control method in the Western world.he rubber vulcanization process was invented by Charles Goodyear in 1839, and patented in 1844. The first rubber condom was produced in 1855, and by the late 1850s several major rubber companies were mass-producing, among other items, rubber condoms.
