This official Mu Lambda Chapter App is for members of the chapter to find out about our events, chat with Chapter members, View Chapter Documents, View Chapter Directory, View our monthly magazine (The Torch) Pay Chapter Dues and much more. The ability to effectively communicate with Chapter members will help us continue to develop leaders, promote brotherhood and academic excellence, while providing service and advocacy for our community. Mu Lambda is Alpha's eleventh alumni chapter, chartered October 1, 1923, in Washington D.C. The chapter was established, in part, in response to the desire of graduate brothers, many whom were initiated into Beta Chapter at Howard University, to give aid to the undergraduate brothers and continue the work of Alpha. Chartered by 22 distinguished men of Alpha, which included Jewel Nathaniel Allison Murray and Jewel Robert Harold Ogle. First Officers: The officers elected at the first meeting were Brother Harold Stratton-President, Brother John Lowery-Vice President, Brother Victor Daly- Secretary, Brother Daniel W. Edmonds-Treasurer, and Brother Nathaniel Allison Murray (Jewel)-Chaplain. Mu Lambda was thus established and was on its way into history! Chapter Legacy There have been six members who served as the General President of Alpha Phi Alpha Fraternity, Inc. and two who served as the Eastern Region Vice President. Mu Lambda is equally proud of our current brothers making their mark in the Washington D.C. community and beyond. Our chapter has many entrepreneurs, activists, political leaders, philanthropists, academicians, ministers and so much more. Our diverse brotherhood age range is between the ages of 25 and 98. We all work together to maximise the brotherhood of Alpha by following the Objective, Mission and AIMS of our Fraternity.
