There is a very nice article about Dr. Russell Wilder, "A Line in the Sand", at the Mayo Clinic site. Dr. Wilder worked with Dr. Frederick Banting, and Dr. Frederick Allen. If you are interested in the history of the use of insulin for diabetics, or ketogenic diets for those with diabetes or epilepsy, it is a lovely article to read. Pioneering doctors working to help. This must have been at the top of the news headlines in the 1920s.
