The chapter was formed by Founder Dr. Marcus P. Blakemore and was one of the first twenty chapters organized. During its infancy, the chapter worked hard to make an impact in the Pittsburgh community. The chapter held numerous social events to unite people who strove for achievement. Edward Harris left Pittsburgh shortly after the founding of the chapter and helped to form Marshall Alumni in Texas in 1928 and served as the Keeper of Exchequer. In the early years of the chapter, meetings were held at brothers' houses and different YMCA's in the area.
