O. A. Battista begins the interview by describing his childhood in Cornwall, Canada, as one of eight siblings born to a poor, uneducated laborer and a housewife. Battista proudly details his family's hard-working nature and the many professional accomplishments of his brothers, who include a chemist and company president and a world-renowned neurosurgeon. Attending McGill University along with his younger brother, Battista earned a B.S. in chemistry while supporting his household by writing epigrams for the Saturday Evening Post.
Upon graduation Battista obtained a research chemist position at American Viscose Corporation, which was owned by Courtaulds, Canada, where his brother was well established and later became president. He worked on the rubber program and other war-related projects until the end of the war, when he married Helen Keffer and began inventing successful commercial products.
Later, his work at American Viscose and its predecessor FMC earned him over sixty-five patents, including patents on viscose molding, novel yarn, pure cellulose, and microcrystalline collagen. Throughout the 1950s and early 1960s, Battista wrote and published several works, including technical scientific texts, popular magazine articles on chemistry, a "human interest" chemistry text, an examination of the potential of psychopharmaceuticals, and several popular non-scientific collections. In the early 1960s, Battista realized the medical applications of microcrystalline collagen and obtained pharmaceutical backing from Alcon to license the substance as the patented hemostat Avitene. American Viscose and Alcon formed Avicon, Inc. in Fort Worth, Texas, and appointed Battista vice president for science and technology; Avicon obtained FDA approval for Avitene Hemostat, which today is used worldwide in hospital operating rooms. In 1974 Battista took early retirement from Avicon to start his own research institute and promote an Olympiad of Science that encourages and facilitates new product innovations. His institute created over fifty-five new products and publishes of Knowledge Magazine.
