School hygiene is considered a primary necessity for all educational facilities globally. Willard S. Small in his compact book Educational Hygiene advocates the importance of physical education at the elementary school level. His work is aimed at improving the health of school children, teaching health habits and the importance of nutrition and growth. Generating public awareness in maintaining health records and demanding health examinations find a focus. He also attempts to address the urgent and acute problem of malnutrition among school children. Social hygiene and sex education, oral hygiene and controlling epidemics in school take a front seat in Small’s important discourse. WILLARD S. SMALL (August 24, 1870 – 1943) is quite famous as an experimental psychologist. Small pioneered the study of using the behaviour of rats in mazes to measure learning. In 1900 and 1901, he authored Experimental Study of the Mental Processes of the Rat that was published in the American Journal of Psychology. Small completed his Bachelor’s degree from Tufts College in 1897 followed by a doctorate degree in comparative psychology at Clark University. He researched the formation of associations, which seemed to be the basis of animal intelligence. His aim was to develop a better understanding of the animal mind and to study the differences among species.
