In WWI he became Chief Inspector of Powders and Explosives at the U.S. Ordnance Dept. Starting 1925, he spent a 34-year career at Griffith Laboratories (Alsip, Illinois) making major advances in the chemistry of food preservation, especially with spices, meats, and vegetable oils. In retirement, he consulted with the Food and Agriculture Organization of the United Nations (FAO) and the Food for Peace Council of USAID Global Health.
