Lloyd Hall

Dr. Lloyd Augustus Hall 1894 - 1971

Lloyd Hall graduated from high school in Illinois, and continued his post secondary education in the same state. In 1914, he earned his Bachelor of Science degree from Northwestern University. Two years later he earned a Master of Science from Northwestern. Years later, Hall earned a doctorate in science from Virginia State College.

Hall put his education to work, and served as a Sanitary Chemist for the Department of Health Laboratories for the City of Chicago. Up for a challenge, Hall left this post after four years and moved to Iowa to serve as chief chemist for John Morrell and Company. Hall served in this capacity in Iowa for two years before returning to Chicago and being named president of the Chemical Products Corporation between 1921 and 1924.

The sky was the limit for this brilliant chemist. After running Chicago’s Chemical Products Corporation for three years, he consulted for Griffith’s Laboratories. Recognizing his gifts and experience, Griffith’s Laboratories named Dr. Hall chief chemist. A few years before retirement, Hall served as technical director and assistant chief inspector of high explosives and research for the U.S. Government during World War I. Hall was asked to postpone retirement and again consulted for the U.S. Government a second time, during World War II.  

After retirement, Dr. Hall consulted for the Food and Agriculture Organization of the United Nations. Hall is the owner of over 100 patents in the U.S., Canada, and the United Kingdom. Most of those patents are related to food preservation. Dr. Hall’s food preservative chemicals are directly responsible for keeping our food fresh and flavorful over extended periods of time.
