Elmer Keiser Bolton
When Wallace Carothers arrived at DuPont in 1928 one of the tasks his group took on was the development of new synthetic fibers for textiles. At that time a number of natural polymers such as latex and cellulose were in common use, rayon as a semisynthetic from nitrated cellulose had recently been improved and begun upending the textile industries, and some fully synthetic polymers such as bakelite were also known and being used for certain applications, but the existing fully synthetic polymers could not be drawn into fibers and spun into thread, so great opportunity existed to manufacture thread and yarn from synthetic polymers to join or replace the existing fibers in the market (natural fibers such as cotton, wool, linen, and silk and artificial fiber in the various recently emerged types of rayon).
Albany Billiard Ball Company
In the 1860s, John Wesley Hyatt of Albany, New York acquired British chemist Alexander Parkes's 1855 patent for Parkesine, an early polymer, made of nitrocellulose, oil and various solvents. Parkes's own attempt to build a business around the new material, the first industrial plastic, had failed by 1868. Hyatt began experimenting with cellulose nitrate with the intention of manufacturing billiard balls, which until that time were principally made from ivory (cheaper balls were made of clay or wood). Using cloth, ivory dust, and shellac, Hyatt devised a method of covering billiard balls with the addition of collodion in 1868.
