Born November 28, 1837, at Starkey, New York [Died] May 10, 1920. Short Hills, New Jersey. American inventor and businessman. He discovered the world's first method of manufacturing the synthetic resin celluloid. As a young man, he worked as a printer in Illinois and Albany, New York. In 1863, a billiard equipment manufacturer in New York offered a $10,000 reward for the invention of a material to replace ivory for billiard balls. Hyatt experimented with several compounds without success. However, he and his brother started a business to manufacture embossed checkers and dominoes using a compound of wood pulp and shellac (→lac) that had been used in the process. During further experiments, he discovered that a beautiful and practical plastic material could be made by kneading nitrocellulose, camphor, and alcohol and pressing them under heat. In 1870, he patented the name celluloid. In 1872, they moved the headquarters of Celluloid Manufacturing, which they founded, from Albany to Newark, New Jersey, and acquired numerous patents, building it into one of the world's leading celluloid manufacturers. In the 1880s, they patented a water purification method using coagulants and filters, and founded a company that handled water purification equipment (→ Water purification). They went on to invent many industrial machines, including roller bearings, sugar cane grinders, and sewing machines. Hyatt |
