The "Rubber King"  --   EX EX RARE hand written ALS letter in 1859  --   this is only the second letter that most advanced collectors have ever seen ---  he is SO RARE --  

Charles Goodyear (December 29, 1800 – July 1, 1860) was an American self-taught chemist^[1][2] and manufacturing engineer who developed vulcanized rubber, for which he received patent number 3633 from the United States Patent Office on June 15, 1844.^[3]

Goodyear is credited with inventing the chemical process to create and manufacture pliable, waterproof, moldable rubber. However, the Mesoamericans used a more primitive stabilized rubber for balls and other objects as early as 1600 BC.^[4]

Goodyear's discovery of the vulcanization process followed five years of searching for a more stable rubber and stumbling upon the effectiveness of heating after Thomas Hancock.^[5] His discovery initiated decades of successful rubber manufacturing in the Lower Naugatuck Valley in Connecticut, as rubber was adopted to multiple applications, including footwear and tires. The Goodyear Tire & Rubber Company is named after him.
