fight overseas, chapter activity was limited. With the war's successful conclusion, Kutschinski helped Delta Chapter reorganize and increase its active membership. Alpha and Delta Chapters met for a National Convention in 1949. The 1950s saw the majority of Chapter activities take place on the local level, with minimal collaboration between the chapters. Despite a desire to meet for a convention every year, they would not do so until 1957. 1960s The 1961 National Convention marked an important milestone for Mu Beta Psi, when the National Constitution was amended to allow membership to women. Additionally, a national publication was created, which would become known as The Clef. New expansion efforts were also put into place. This was also the first of an unbroken chain of annual conventions that continues to this day. The Fraternity saw additional changes in both leadership and expansion. Kutschinski stepped down as National Executive Secretary in 1962. Three years later, Ralph W. Daniel was elected to the position and would serve for the next 18 years. Two new chapters were installed, the first in nearly two decades. One was Epsilon Chapter at Washington & Lee University in 1965, which would remain active for nearly 20 years. The other was Zeta Chapter at Michigan Technological University in 1967, which was the result of a successful merger with Tri-Beta Honorary Band Fraternity. Zeta remains active to this day. 1965 also saw the adoption of the "Editor of The Clef" as a National Officer. "Hail the Spirit," written by Milton C. Bliss, was adopted as the Fraternity Song in 1967. 1970s and 1980s The fraternity continued a period of gradual expansion in the 1970s and 1980s. The Alumni Association was formally established in early 1970, providing college graduates with a chapter to continue their participation in the fraternity's activities. The short-lived Eta Chapter was installed at Virginia Military Institute in mid-1970. Theta Chapter was established at Saint Augustine's College in 1973, and remained active for 13 years. Iota Chapter was established at Duke University in 1981 and went inactive 3 years later. Kappa Chapter was established at Wofford College in 1989 and stayed active for 7 years. The mid-1980s also saw the creation of the Permanent Board of Trustees for the purpose of ensuring stability in the organization. The first members of the Permanent Board included Wallace DesChamps, Charlie Emki, David Wilson and Bryan Reamer. 1990s Mu Beta Psi underwent
