Charles Goodyear (1800-1860) was an American self-taught chemist and manufacturing engineer. He is famous for inventing vulcanized rubber. This process made rubber stronger and more elastic. Before Goodyear, rubber would melt in the summer heat and become brittle in the cold. Think of vulcanization as baking a cake 🎂; the heat transforms the ingredients into something completely new and durable. Goodyear's invention revolutionized industries, from tires to raincoats.
