Our History
We are proud that Alpha Delta Pi was the first secret society for college women. Our founders Eugenia Tucker Fitzgerald, Elizabeth Williams Mitchell, Sophronia Woodruff Dews, Octavia Andrew Rush, Mary Evans Glass, and Ella Pierce Turner started this first secret society named the Adelphean Society at Wesleyan Female College in Macon, Georgia, May 15, 1851. The name comes from the Greek word for sister. To date, Alpha Delta Pi has over 155 collegiate chapters.

In addition to the Constitution, the Founders selected the native woodland violet as the official flower. They chose colors—azure blue for friendship and white for sincerity and truth. They embraced the motto Eugenia had selected, “We Live for Each Other,” and they selected the clasped hands as a symbol of friendship. In 1852, just one year after the founding, the blue and white ribbon badge was replaced with a diamond-shaped badge with clasped hands. Modifications have been made over the years, but the diamond shape with clasped hands remains the same.
