Russell M. (Russell Morse) Wilder

Born in Cincinnati in 1885, Russell M. Wilder was an American physician and medical researcher whose career became closely tied to diabetes and nutrition. He studied at the University of Chicago and Rush Medical College, and he later worked at the Mayo Clinic, where he built a reputation in metabolic medicine.

Wilder is especially remembered for coining the term "ketogenic diet" and for helping develop its early medical use, particularly in the treatment of epilepsy. He was also among the early American physicians to use insulin for patients with diabetes, and he wrote books and patient guides that aimed to make treatment clearer and more practical.

He died in 1959, but his influence has lasted far beyond his own era. His name still comes up in the history of diabetes care, clinical nutrition, and the medical roots of what is now widely known as keto.
