"The data gathered from the physical examinations and the laboratory tests, as well as similar information acquired from the control group, accumulated rapidly. Some mechanism was necessary for storing the large volume of data, sorting it and preparing it for study . . . Great was the rejoicing upon the arrival of an updated replica of the data processor I had seen demonstrated at the National Library of Congress. Our New equipment was said to have the largest capacity for data storage and processing of any such equipment west of the Mississippi River"
