Sigma Chi was founded on June 28, 1855, by seven undergraduate men at Miami University. They felt that the principles of “fraternity” were crucial to the overall college experience, but were dissatisfied with the unbalance of loyalties and ideals within the fraternities which existed at their university. Six of the Sigma Chi founders were members of the 12-man Delta Kappa Epsilon fraternity at Miami University; when a controversy arose involving a member of the fraternity which could not be resolved, the membership was divided equally. The actions from this controversy led to the founding of Sigma Chi.
On April 19 1902, the Rho Rho chapter received its charter, with Fraternity Founder Benjamin Piatt Runkle (who was then a military science professor on campus) speaking at the initiation. The first meeting was April 21 of that same year. The current Sigma Chi Heritage house was built in the summer of 1935, and was purchased by the University of Maine in 1998. The chapter is still strong today, and in 2002 celebrated their 100-year anniversary on campus. Notable Rho Rho alumni include Raymond Fogler, Frank Pickering, Richard Salisbury and John Huddilston.
