John Wesley Hyatt (born 1837) started his working life as a printer. Early in his career, he took out a patent for a composition for artificial ivory billiard balls, which led him to the invention of celluloid in 1868. In 1869 Hyatt and his brother Isaac founded the Celluloid Manufacturing Company. He held some 250 patents, mostly concerned with the use of celluloid.
