Alpha Delta Pi | Zeta Lambda | 1500 Athens Drive College Station, TX 77840


Alpha Delta Pi was founded as the first secret society for women in 1851 at Wesleyan Female College in Macon, Georgia. Led by Eugenia Tucker Fitzgerald, our founders formed The Adelphean Society — later renamed Alpha Delta Pi— for “the mental, moral, social, and domestic improvement of its members.” The Zeta Lambda Chapter was founded on August 30, 1975 at Texas A&M University.

"The Society shall be called Adelphean, and shall have for its object to the mental, moral, social and domestic improvements of its members.”
Eugenia Tucker Fitzgerald, Founder


ADPi's are bright, fun, and lovely young women who share the strong bond of sisterhood. The qualifications for membership have remained throughout the years: scholarship, high principles, and true friendship. Here at Texas A&M, we uphold these fine characteristics that make an ADPi sister so special.


Our sisterhood is more than a friendship, it is a bond that lasts forever. Over the last 167 years Alpha Delta Pi has initiated over 235,000 women. Many alumnae sisters actively service one of our 160 chapters as an advisor or international officer. Additionally, ADPi offers over 150 alumnae association across the great United States and Canada. The Zeta Lambda alumnae network is a close-knit group of women who are actively involved in supporting the chapter, well after graduation. It’s not just for four years, but for life.



The first diamond-shaped badge was worn by the Adelpheans in 1852. The badge we wear today showcases the clasped hands of Adelphean friendship, the two stars, and the greek letters, Alpha Delta Pi.
