Plastics industry publisher and trade show founder Charles W. Cleworth died July 27 at his Denver home of pancreatic cancer. He was 69.
Colleagues remembered Cleworth as an innovator and pioneer, a man who introduced the tabloid-style paper to the plastics industry and possessed the foresight for niche magazines. He began his career with his father, C. William Cleworth, who founded Plastics World.
Together with business partner Peter Zacher, Charles Cleworth founded Industry Media Inc. in 1971, the umbrella for Plastics Machinery & Equipment, Plastics Design Forum and Plastics Compounding magazines.
The younger Cleworth also originated the Plastics Fair trade shows. But Cleworth's publishing activities extended beyond plastics. He acquired Radio Communications Report in 1987. In 1988, he was elected chairman of the American Business Press, an industry organization for business publishing. He also was a member of the Plastic Pioneers Association and the Society of Plastics Engineers.
``He gave an awful lot of people in the industry a wonderful foundation in the publishing business and in plastics,'' said Suzy Witzler, who served as the first editor of PM&E and editorial director for Cleworth's publications. ``He left a great legacy behind him.''
Beyond his publishing activities, Charles Cleworth served as president of the University Club of Denver and president of the Board of Trustees for the Denver Botanic Gardens.
``He retired and had a full life,'' Zacher said in a July 29 telephone interview. ``He had a great time. He wasn't angry, because he realized he had done an awful lot in his life.''
Survivors include his wife, Sheila, and sons Montgomery and Peter.
