The brief personal history for the individual subjects which follows includes the full name, date of birth, home address, age at the beginning of the experiment, height, initial nude weight, and the result of the preliminary physical examination by Dr. Walter H. Chapin of Springfield, Massachusetts. Under "personal data" are included various miscellaneous incidents during the progress of the experiment, more especially those relating to the physical condition of the subject. The physical characteristics of the family of the subject are given under "family history." The course taken in college and the physical activities of the subject are likewise included in the data. The personal histories for Squad A are naturally more detailed than those for Squad B. For subsequent reference in a large number of tables, abbreviations of the names of the subjects seemed essential. Consequently throughout the book, the men are usually designated by the first three letters of the surname in each case. The personal history of each man is given under this arbitrary designation for ready reference.
