I was looking up information about plastics, and ran across this:

"...the U.S. plastics industry officilly dates its beginnings back to 1868, when a product called Celluloid was created as the first commercial plastic in the U.S. The development was in response to a competition sponsored by a manufacturer of billiard balls. It came about when a shortage developed in ivory from which the billiard balls were made..."

Hyatt, John Wesley (1837-1920)
US inventor who in 1869 invented celluloid, the first artificial plastic, intended as a substitute for ivory. It became popular for making a wide range of products, from shirt collars and combs to toys and babies' rattles, and is still used in the manufacture of table-tennis balls.
Hyatt was born in Starkey, New York, and worked in Illinois as a printer. In the early 1860s, the New York company of Phelan and Collender offered a prize of $10,000 for a satisfactory substitute for ivory for making billiard balls. Using pyroxylin, a partly nitrated cellulose, Hyatt developed celluloid (the US trade name: it was called Xylonite in Britain). Although celluloid did come to be used for billiard balls, Hyatt was never awarded the prize money. He continued to patent his inventions - more than 200 of them, including roller bearings and a multiple-stitch sewing machine.
Celluloid consisted of a mouldable mixture of nitrated cellulose and camphor. Its chief disadvantage was its flammability. Celluloid was also used as a substrate for photographic film and as the filling in sandwich-type safety glass for car windscreens. It has largely been superseded by other synthetic materials.

Apparently Mr. Hyatt's billiard balls tended to explode when they struck one another at high speeds.
