Scope and Contents
The papers of Edwin Hoyt Lockwood (1866-1930) are contained in two manuscript boxes, one of automobile chassis dynamometer tests and an explanation of the methods used and calibration calculations, and one containing a laboratory experiment notebook kept in 1893.
The body of this collection is a series of automobile chassis dynamometer tests which Lockwood and his students performed from 1916-1931. Virtually all the great classic cars are represented even though the collection is not complete. Professor Lockwood numbered the series of tests 100-435, but this collection contains only approximately 200 of the 345 original tests. These are blueprint copies of the original test information. The originals of the series were deposited in the Ford Museum, Dearborn, Michigan. Along with the copies of the original tests is an explanation of the testing methods and calculations used in calibrating the measuring equipment.
There are also two studies of independent engineering problems: a calculation of the Frequency of A Mallable Iron Fittings Company, (Branford, Conn.) Vibrator and the correspondence concerning the problem, and a study of Centrifugal Force and Coiled Springs.

Biographical / Historical
Edwin Hoyt Lockwood was born October 31, 1866, in New Canaan, Connecticut. He prepared for Yale at the New Canaan Seminary and received his Ph.B. from Sheffield Scientific School in 1888. He continued to be associated with the scientific divisions of Yale until his death. He received his M.E. in 1892 and his Ph.D. in 1901. He began as an instructor in the Department of Mechanical Engineering and continued in that department steadily rising in rank until he was appointed Robert Higgins Professor of Mechanical Engineering in 1927. He was a member of the American Society of Engineers, The Society of Automotive Engineers, the Society of Mechanical Heating and Ventilating Engineers, The American Academy of Arts and Sciences, and other engineering societies. He contributed articles to The Journal of Automotive Engineers, Power, The Scientific American, and the Yale Alumni Weekly. He also wrote a pamphlet on mechanical drawing (Tuttle, Morehouse, and Taylor, 1892), and contributed a chapter on perspective to John Clayton Tracy's Introductory Course in Mechanical Drawing(New York, 1898).
His real reputation came not from mechanical drawing, but from the development of experimental mechanical and automotive engineering in which he played a part. He came to be respected as the leading authority in the scientific aspects of automotive design and testing, and in the late 1920's performed automotive tests on new models for the companies which produced them. His tests were as authoritative as the road tests conducted by independent testing companies today, in the days before road tests became standard.
