The Alpha Omicron Chapter of Lambda Chi Alpha has a long and proud heritage. Founded in 1917 on the campus of Indiana University, it is one of the oldest active chapters in the fraternity. Over its more than 100-year history, this chapter has been home to some of the most influential members of Lambda Chi Alpha as well as many successful alumni who have gone on to make their mark in various fields. From scientists and engineers to business leaders and politicians, these men are all part of the legacy that makes up Alpha Omicron's rich heritage.


Lloyd Claycomb was AO's first initiated member of the chapter. Other notables include Harold Mumby, AO 99, who in addition to being a multi-sport athlete, coach and Indiana Football Hall of Fame inductee, is claimed to be one of the Ghosts of 1210 East Third St. along with AO, Hence Orme.

In addition to ghosts and HoFers, AO alumni include doctors, lawyers, judges, educators, electricians, NBA executives and other walks of life. Be sure to join our LinkedIn group and connect with AOs from around the world.

Lambda Chi Alpha and the Acquisition of a Permanent Home


In 1917, the male members of the society decided to explore affiliation with a national fraternity to enhance their competitiveness. Impressed by Lambda Chi Alpha's leadership, the society members petitioned to join. Lambda Chi Alpha granted a charter to Alpha Omicron Chapter at IU on May 12, 1917.


The chapter, comprising twenty-two men including founding members Lloyd Claycombe AO 1, Glen R. Hillis, and Vilmer Tatlock, continued to occupy the Literary Society's house. In 1919, the chapter incorporated with the State of Indiana and formed the AO Housing Corporation. The chapter embarked on a journey to acquire land and build a dedicated house, which was completed in 1925 at 1210 East 3rd Street.

The Alpha Omicron Chapter at Indiana University has left an indelible mark on the university's history. From its early beginnings as the Independent Literary Society to its affiliation with Lambda Chi Alpha, the chapter has embodied the principles of brotherhood, service, and academic excellence. As it looks toward the future, the Alpha Omicron Chapter remains committed to upholding its traditions, supporting its members, and making a positive impact on the IU community.


The Alpha-Omicron chapter at Indiana University has accomplished something remarkable that only few chapters can boast -- more than 100 years of continuous operation! In April of 2017, a celebration of 100 years kicked off with past and present brothers gathering at the chapter house to share memories and participate in a moving time capsule ceremony. The centennial was more than just a milestone, it represented a proud tradition of Lambda Chi Alpha in Bloomington that has lasted a lifetime.

Undergraduates and alumni enjoyed the day getting to know each other and sharing experiences. The alumni, who have not visited for years, marveled at how the fraternity had changed over time while still maintaining some of its traditions.


As the evening approached, members migrated to Alumni Hall in Indiana’s student union building for a dinner and banquet. They heard from dynamic speakers and came together to discuss their future. As the celebration drew to a close, almost 400 attendees were challenged: to tackle another 100 years as proud members of Lambda Chi.
