The Brief Military Career of Dr. William H. Welch.

Introduction: The purpose of this article is to examine the Army service of Dr. William H. Welch during World War I. Materials and

Methods: Archival research utilizing prime source documents in the William H. Welch Collection of the Alan M. Chesney Medical Archives for the Johns Hopkins Medical Institutions.

Results: Welch joined the Army at the age of 67 after serving as one of the principal transformational forces for reforming medical education in the United States and founding the first academic institution for educating public health professionals in the United States, the Johns Hopkins School of Public Health and Hygiene. His longstanding relationship with Army Surgeon General William Gorgas served as the backdrop for Welch's service. Welch served as both a staff officer and as a traveling medical inspector general, assessing the medical care of troops preparing for overseas duty. He did not adapt particularly well to military dress and decorum but his status as one of the icons of American medicine rendered these shortcomings insignificant. Welch was joined in Army service by a number of American medical luminaries-both Mayo brothers, George Crile, and Harvey Cushing among them. Although Welch remained on active duty for only 13 months, he maintained a nominal relationship with Army medicine through appointment to the Medical Officer Reserve Corps until the time of his death.

Conclusion: 2016 marks the centennial of the establishment of the first independent academic institution in America dedicated to education and training of professionals focused on public health and hygiene issues. 2017 marks the centennial of U.S. entry into World War I. Dr. William H. Welch played an important role in both of these historic events and, although his active service was brief, the impact of his example was substantial. Analysis of his military career in its full historical context provides insight into the relationship between academic medicine and military medicine during periods of armed conflict.
