Who discovered the process of vulcanization?

Charles Goodyear
John Boyd Dunlop
Edouard Michelin
Giovanni Battista Pirelli
Charles Goodyear for many years improved the method of hardening the rubber. When he succeeded in 1839, investors were already offended by earlier failures. Charles died in misery. The Goodyear company was named in his honor, but otherwise is not related to him.
