Alpha Delta Pi is recognized as the first secret society in the world for college women. Appropriately, Alpha Delta Pi was founded at Wesleyan College in Macon, Georgia, the first college in the world to grant college degrees to women.  Six women enrolled at the school, Eugenia Tucker Fitzgerald, Ella Pierce Turner, Octavia Andrew Rush, Elizabeth Williams Mitchell, Sophronia Woodruff Dews, and Mary Evans Glass, founded the Adelphean Society on May 15, 1851, naming their society after the Greek word for "sister."  In 1905, the Adelphean Society became a national organization, taking the name Alpha Delta Phi, and joined the National Panhellenic Conference in 1909.  After discovering that another organization named Alpha Delta Phi existed, the sorority changed its name to Alpha Delta Pi in 1913.



     Alpha Delta Pi's colors are azure blue and white; azure blue signifying friendship, and white symbolizing sincerity and truth. The sorority's symbol is the diamond, its mascot is the lion, and the official flower is the violet.  The open motto is "We Live for Each Other." Since 1979, Alpha Delta Pi's philanthropy has been the Ronald McDonald House, to which the sorority has donated over $2 million and countless volunteer hours.

Today, Alpha Delta Pi has over 140 chapters and has initiated more than 215,000 members. The Eta Beta chapter of Alpha Delta Pi was founded at Allegheny College in 1983.
