Which car essential was invented by Edouard Michelin?

Brothers André and Édouard Michelin revolutionized pneumatic tire technology. André, the eldest of the brothers, was born in 1853 in Paris, France. His younger brother Édouard was born six years later in 1859 in Clermont-Ferrand, France. Both brothers had aspirations of embarking on their own careers. André was a renowned engineer and Édouard showed great promise as an artist. Edouard in 1891 was granted a patent for a detachable-pneumatic tire. The Michelin brothers soon became leading tire suppliers to the fledgling automotive industry, and even today Michelin is one of the largest and most respected tire suppliers in the world.
