John Joseph Cislo, 78, of Harrison, New Jersey, died Friday, July 11, at Clara Maass Medical Center in Belleville, New Jersey.
Born in Dupont, he was a son of the late Elmer and Nellie Cislo. He graduated Dupont High School in 1948. John was an Air Force veteran who was stationed in Wyoming, California and Korea. He attended St. John’s University, and later worked as a research chemist at laboratories such as IBM, Thiokol, and Combustion Engineering-Lummus, from which he retired.
During his career, he was responsible for cutting-edge research and innovations such as the rocket fuel that powered the Apollo missions and industrial clean-room technology that dramatically improved semiconductor manufacturing yields.
John enjoyed hunting and was an avid reader, a legacy that he was able to pass on to his family. He was knowledgeable in politics, the sciences and history. He had a lifelong interest in the cultivation and breeding of rare plants and orchids. John enjoyed sharing stories, conversations and lively discussions.
He will be deeply missed by his family and friends. No matter how far he traveled, he never lost sight of the beloved Pennsylvania forests that he played in as a child. He returned each year for the high school reunion, to see his former classmates.
He was preceded in death by his wife, Toni Cislo, who passed away in Dec., 2007. They had celebrated their 55th wedding anniversary on Valentine’s Day of that year. Even in their last year they were lucky enough to still go on dates together.
