Since the fraternity had gone national in 1921, the leaders at the national level had been faculty advisors of the chapters and active alumni. By 1950, not only was contact with alumni critically affected due to the war, but the faculty advisors who guided the fraternity through most of the previous two decades were ready to retire. By 1954, Clair B. Wilson, James M. McCallister, Alpha 33, James K. Stoner, and long time Regional Director Simon S. Shearer, Omicron 20, were gone. Death claimed Beecher Flanagan in 1950 and Sanders P. McComsey, Sigma 17, in 1955. The Regional Director system was retired in order to utilize the leadership of the National Officer positions. Also at this time, The Lampadion ceased publication, leaving the Purple & Gold as the sole communication between the chapters and the National Office. However, at the close of the decade the fraternity was incorporated nationally in Illinois on April 25, 1949.
