Mayor John Francis Fitzgerald temporarily appointed him Port Physician in February 1911 when Paul Carson, the Port Physician, was placed in charge of the Board of Health’s Department of Child Hygiene. By the following month the Mayor appointed him the 16th Port Physician of the city with an announcement of his promotion carried in the March 14, 1911 issue of the Boston Daily Globe. His reign in that position was one of the shortest in the history of the Boston quarantine establishment. He resigned six months later on September 1, 1911. He had battled communicable diseases on Gallop’s Island for longer than any other assistant port physician. His battles against deadly diseases prepared for his next mission in life. Soon thereafter he joined the Army and rose to the rank of Major as a Medical Officer in World War I, cited for his bravery. As a Major in the World War, Dr. Gay won a citation for bravery when the hospital in which he was performing surgical operations at Verdun was bombed. He distinguished himself at Chateau Thierry also.
After the war Dr. Gay worked for the Veteran’s Administration with his last assignment at the Sunmount Hospital near Lake Placid, New York where he supervised the veteran’s administration facilities. He died on May 13, 1933 and was buried in Arlington National Cemetery.
