Charles Goodyear (December 18, 1800 – July 1, 1860) was an American self-taught chemist〔 〕〔 〕 and manufacturing engineer who developed vulcanized rubber, for which he received patent number 3633 from the United States Patent Office on June 15, 1844.〔(United States Patent Office )〕 Though Goodyear is often credited with the invention of vulcanized rubber, modern evidence has proven that the Mesoamericans used stabilized rubber for balls and other objects as early as 1600 BC.〔Hosler, D., Burkett, S. L., and Tarkanian, M. J. (1999). "Prehistoric polymers: Rubber processing in ancient Mesoamerica," ''Science'', 284(5422), pp. 1988–1991.〕 Goodyear discovered the vulcanization process accidentally after five years of searching for a more stable rubber and stumbling upon the effectiveness of heating after Thomas Hancock.〔Slack, Charles (2003). ''Noble Obsession'', 225, Hyperion. ISBN 0-7868-8856-3.〕 ==Early life== Charles Goodyear was born in New Haven, Connecticut, the son of Amasa Goodyear, and the oldest of six children. His father was a descendant of Stephen Goodyear of London, Middlesex, England, one of the founders of the colony of New Haven in 1638.〔(Leading American Inventors, 1912 )〕 In 1814, Charles left his home and went to Philadelphia to learn the hardware business. He worked industriously until he was twenty-one years old, and then, returning to Connecticut, entered into partnership in his father’s business in Naugatuck, CT where they manufactured not only ivory and metal buttons, but also a variety of agricultural implements. 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Charles Goodyear」の詳細全文を読む スポンサード リンク
