   INTRODUCTION
 
Epidemiology came to the forefront in 1933! That year, the Editors decided to devote the last of the three issues in each volume of the American Journal of Hygiene primarily to epidemiologic topics. These epidemiologic issues could be purchased separately, making them one of the earliest epidemiologic "journals."

The corollary of this decision was that the first two issues of each volume were likely to contain little of interest to epidemiologists. There were two exceptions in 1933. Volume 17 contained a review of the immunologic effects of vitamin A and D deficiencies, accompanied by a report on the author’s experimental work with rabbits (1). Vitamin A-deficient rabbits showed a markedly diminished response to immunization with sheep or ox red cells, while controls and vitamin D-deficient animals responded normally. Both A deficiency and D deficiency were associated with increased susceptibility to infections with Bacterium lepisepticum and type I pneumococci.
