During the tumultuous period of the Second World War, Dr. Harvey’s public service extended significantly to civil defense. Dr. Harvey was in charge of the Casualty Services in Southgate during the blitz, and he played a crucial role in leading the civil defense casualty service in Southgate, coordinating responses to wartime emergencies and ensuring public safety. Towards the end of 1942, when “things seemed quiet” at home, he was given permission to join the Armed Forces and, in 1943, joined the Royal Army Medical Corps (R.A.M.C.), directly contributing his medical expertise to the war effort.
In 1944, he was sent to Western Europe, first to Belgium and France, and later into Germany. “I enjoyed every minute of my stay in France,” he said. “I learnt a great deal, I saw what other people were trying to do, I found my experiences as a Medical Officer of Health invaluable.”
In Germany, he was put in charge of the many camps on the bank of the Rhine through which prisoners of war and deported nationals from Western Europe were continuously passing. He had to reorganize the medical services for these camps, open hospitals, appoint medical officers, make arrangements for babies to be born, treat cases of typhus fever, and arrange for surgical operations to be carried out.
He also had the even more difficult job of getting the German Public Health system in his area back on its feet. “I used to have to go to small towns,” he said, “see the Burgomaster and ask for the Medical Officer of Health. If there was no Medical Officer of Health—and, believe me, there seldom was one—I paraded the few general practitioners, mostly old men, who still remained and made an appointment.”
Medical supplies were almost non-existent, supplies of diphtheria antitoxin unavailable, even during an epidemic, and anesthetics in very short supply. He said if he had known the extent of the problems before being sent, it would have given him a nightmare. Once his work in Europe was completed, Dr. Harvey returned to civil life in 1946, with the honorary rank of Lieutenant-Colonel.
