Jonas Walter Aylsworth

(1868 - 1916)

A gifted chemist, Aylsworth began working at Thomas Edison's West Orange lab when they opened in 1887. Much of his work involved testing materials for phonograph recordings. He became Edison's chief chemist but left around 1891 only to return ten years later, working both for Edison and in his own laboratory. He patented condensite, a mixture of phenol and formaldehyde, for use in Edison Diamond Disc records. His work with "interpenetrating polymers" came decades before other scientists made similar discoveries with plastics.

Jonas was inducted into the Plastics Hall of Fame on October 2 1996. (Photo of Award)
