Charles Goodyear (1800–1860) was a self-taught American chemist and engineer who revolutionized the rubber industry. For years, he struggled with poverty and debt while trying to make rubber durable. In 1839, he accidentally discovered the process of vulcanization by dropping a mixture of rubber and sulfur onto a hot stove. This breakthrough transformed rubber from a sticky, heat-sensitive substance into a tough, weatherproof material used in millions of products today.

Revolutionary Vulcanization: He invented the process that made rubber resistant to extreme heat and cold, forming the foundation of the modern tire industry.

Unwavering Persistence: Despite spending years in debtors’ prison and facing constant business failures, he never stopped experimenting to perfect his invention.

Lasting Global Legacy: Although he died in debt, the Goodyear Tire & Rubber Company was named in his honor 40 years later to celebrate his massive contribution to science.
