Joseph Davol, 1837-1909, was a pioneer in the rubber industry who, prior to incorporating the Davol Rubber Company in 1881, devoted much of his time to experimentation and invention in the processing of rubber. He was among the first to see the potential for rubber products in the fields of medicine and dentistry. He remained the President, Treasurer, and general manager of this major business enterprise until his death in 1909.
