in 1990 “for pioneering analytical simulation of internal combustion engines and verification with advanced experimental techniques.”
Gary had a keen interest in gardening. He and his wife Marlene always landscaped their home garden personally and kept it in excellent shape. He traveled throughout his career and after retirement traveled for personal pleasure with Marlene. They went to Europe, England, Spain, Switzerland, Yugoslavia, Egypt, Japan, and the Scandinavian countries, and they traveled extensively in the United States. Their interests were in seeing the gardens, parks, and museums of each country. Gary kept up an active interest in history, economics, and current affairs and was an avid photographer. In addition, he was a fine cook and entertained friends regularly at his home.
His impact on the internal combustion engine community, his colleagues at the university, his students, and his many friends was immeasurable. His spirit lives on in all who knew and worked with him.
