My interest was directed, from my medical student days, to Immunology, and particularly to the mechanism of hypersensitivity. I had suffered from bronchial asthma as a child and had developed a deep curiosity in allergic phenomena.

While in medical school, I was drafted into the U.S. Army with the other medical students as part of the wartime training program, and naturalized American citizen in 1943. I greatly enjoyed my medical studies, which at the Medical College of Virginia were very clinically oriented.
