J. Paul Hogan

John Paul Hogan (August 7, 1919 was an American research chemist. Along with Robert Banks, he discovered methods of producing polypropylene and high-density polyethylene. However, in a series of experiments, and after having added chromium as a second transition metal promoter, the scientists created crystalline structures. These plastics were initially known by the name Marlex. He held (jointly) a number of important patents and authored research papers before he left Phillips in 1985.

After a few years as an independent consultant, he fully retired in 1993.

In 1987, he and Robert Banks together received the Perkin Medal Award and both were given a Heroes of Chemistry award by the American Chemical Society in 1989. In 2001, they were inducted into the National Inventors Hall of Fame. Dr. Hogan was inducted into the Plastics Hall of Fame in 2014.
