What Did Charles Goodyear Invent?

Old Charlie is credited with the discovery of vulcanized rubber although evidence proves that earlier civilizations used materials in a similar form as early as 1600 BC. Mr. Goodyear stumbled upon this state on accident whilst researching a more stabilized rubber. The Goodyear company was formed posthumously and has become synonymous with tires. Don’t go to the Goodyear on Whitlock Avenue. Those dudes are crooks. Just sayin’.
