Vulcanization was invented in 1839 by Charles Goodyear.

Here's a quote from some online encyclopedia:

As much as 47 parts of sulfur can be combined with
100 parts of rubber, resulting in a compound containing 32
percent sulfur. Such a product is hard and tough, and is
known as ebonite because of its resemblances to ebony wood.
It is also called vulcanite or hard rubber. The term hard
rubber is generally applied to vulcanites of rubber and
sulfur containing more than 20 percent of combined sulfur.
