The successful carrying out of the experiments in all their details,
especially the chemical work, has been rendered possible by the active
and continuous co-operation of the writer’s colleague, Lafayette B.
Mendel, Ph.D., Professor of Physiological Chemistry in the Sheffield
Scientific School.
Efficient aid in the routine chemical and other work of the laboratory in
connection with the experiments has been rendered by Frank P. Underhill,
Ph.D., Arthur L. Dean, Ph.D., Harold C. Bradley, B.A., Robert B. Gibson,
Ph.B., Oliver E. Closson, Ph.B., and Charles S. Leavenworth, Ph.B.
Dr. William G. Anderson, Director of the Yale Gymnasium, with the
co-operation of his assistants, has rendered valuable aid in looking
after the physical development of the men under experiment, in arranging
for frequent strength tests, as well as in prescribing the character
and extent of their work in the Gymnasium. The greater portion of the
training of the soldiers was under the personal supervision of William
H. Callahan, M.D., Medical Assistant at the Gymnasium, while Messrs.
William Chase, Anton Muller, John Stapleton, and H. R. Gladwin, Assistant
Instructors in the Gymnasium, led the drills and looked after the actual
muscular training of the men.
In the study of “Reaction Time” and other matters of psychological
interest the work was under the direction of Charles H. Judd, Ph.D., in
charge of the Yale Psychological Laboratory, aided by Warren M. Steele,
B.A., and Cloyd N. McAllister, Ph.D.
In the morphological study of the blood, etc., Dr. Wallace DeWitt,
Lieutenant in command of the Army detail, rendered valuable aid. Dr.
DeWitt likewise co-operated in all possible ways during his stay in New
Haven to maintain the integrity of the conditions necessarily imposed on
the soldier detail in an experiment of this character.
Further, acknowledgments are due the several non-commissioned officers
of the Hospital Corps for their intelligent co-operation and interest.
Finally, to the men of the Hospital Corps who volunteered for the
experiment, our thanks are due for their cheerful compliance with the
many restrictions placed upon them during their six months’ sojourn in
New Haven, and for the manly way in which they conducted themselves under
conditions not always agreeable.
To the students of the University who volunteered as subjects
of experiment our acknowledgments are due for their intelligent
co-operation, keen interest, and hearty compliance with the conditions
imposed.
