Story of Service


My Grandfather, Dr. Leonard A. Crosby graduated from the University of Tennessee School of Medicine and completed an internship as a surgeon. He enlisted in the Army at the start of America's involvement in that war and was commissioned a Captain in the Army Medical Corps.

I do not know what unit he was assigned to, but I do know that he deployed with the first contingent of troops sent to France, and served as a Physician and medical officer until the end of the war. I also know that he was involved in the Ardennes campaign and similar actions in that area with his unit.

After the War, he became a family physician in Kentucky and Mississippi, and was one of the first physicians to utilize insulin to treat diabetes. At one point in his career, he was asked to join the Mayo Clinic in Minnesota, but chose not to relocate and continued to practice medicine and surgery until his late 60's, acting in several administrative roles at local hospitals in Marion, Kentucky and Aberdeen, Mississippi.
