to work on a research fellowship project on a topic suggested by the Bethlehem Steel Corporation "structural beams in torsion." This work, involving both the application of Prandlt's soap film analogy and tests of actual members in torsion, resulted in the development of formulas that eventually permitted the accurate calculation and tabulation of St. Venant's torsion constant for rolled WE and I sections in the AISC (American Institute of Steel Construction)

Johnston was in charge of structural research programs at Lehigh's Fritz Engineering Laboratory from 1938 until 1950, except for a two-year interruption during World War lI while he was first a design engineer for the U.S. Navy Bureau of Yards and Docks and then engaged in the study of vibration and shock-Ioad problems related to the development of the proximity fuse and naval gun directors at the Johns Hopkins Laboratory of Applied Physics.

Early research at Lehigh in the 1940s stimulated his interest in attaining a better understanding of metal column behavior, a topic that thereafter became a primary thread ot Interest. One of my earliest projects at Lehigh concerned the behavior of eccentrically loaded steel columns, a study sponsored by the American Institute of Steel Construction.

He was in charge of the evaluation of test results for one group of industrial and commercial buildings under a contract with the Federal Civil Defense Administration. During the 1960s and early 1970s, he was active as a consultant to the Association of Iron and Steel Engineers, assisting in the development of structural specifications for steel mill ladIes, overhead traveling cranes, and mill building structures.
