As a result of his early efforts, several of the nine chemical depots at which chemical weapons were stored adopted alternative disposal technologies. For example, neutralization of an agent by sodium hydroxide has been successfully used to destroy the nerve agent VX at the Newport, Indiana, chemical depot and is planned to be used to destroy mustard blister agent at the chemical depots in Pueblo, Colorado, and Blue Grass, Kentucky.
Jack contributed his time freely to professional societies. He received the 1979 Award in Chemical Engineering Practice from the American Institute of Chemical Engineers in recognition of lifetime contributions. He was involved on the governing committees of the Combustion Institute since it was founded in 1954, serving on its board of directors and a term as its president, contributing to the growth of the institute into the preeminent international organization in combustion. He was the recipient of the 1974 Alfred C. Egerton Gold Medal, awarded by the institute for distinguished, continuing, and encouraging contributions in the field of combustion. He was elected to the National Academy of Engineering in 1976.
Jack brought to his hobbies of fishing, hunting, jewelry making, and woodcarving the same intensity that he applied to his professional activities. He was an enthusiastic woodcarver who produced furniture and figurines that graced his home; he often used wood from the trunks of trees downed in his neighborhood during storms. To make hunting more competitive, he used bows that he had designed and built. He was an avid fisherman; one of his favorite spots to fish was in the Henry’s fork of the Snake River in Idaho, where his cabin was situated in the Yellowstone Caldera, with a distant view of the Grand Tetons. The cabin was designed by the architect husband of his daughter Ann and was built as a joint effort by Ann and his son John, along with John’s college-age friends. Jack was responsible for carving the dovetail joints for the close to 400 logs used to build the three-bedroom home, joints that locked together so perfectly that the house was impermeable and beautifully insulated. The cabin continues to be a family gathering place and continues to be enjoyed by Ann and her family.
