Sigma Chi

Our History

Sigma Chi (ΣΧ) is one of the largest Greek-letter social fraternities in North America with 244 active chapters in the United States and Canada and more than 345,000 initiates. Sigma Chi was founded on June 28, 1855 at Miami University in Oxford, Ohio. The seven founders of Sigma Chi are Thomas Cowan Bell, James Parks Caldwell, Daniel William Cooper, Isaac M. Jordan, William Lewis Lockwood, Benjamin Piatt Runkle and Franklin Howard Scobey.

Sigma Chi is committed to the ideals of friendship, justice, and learning. We seek to build brotherhood and life-long membership among members from all walks of life. Our brothers become values-based leaders committed to the betterment of character, campus and community

Lambda Pi Chapter

The Sigma Chi chapter at Carnegie Mellon was colonized on October 14, 2010 when 23 young men pledged to live the ideals of the Jordan Standard. Since the founding fathers began their work that day, the Lambda Pi chapter of Sigma Chi has experienced tremendous growth, becoming one of the preeminent leadership and leadership development organizations on campus. Focusing on service, community impact, and campus involvement, we strive to live by the high ideals of the Sigma Chi Fraternity and promote community involvement and lofty ambitions in our college, community, and the world.
