ADG Founders.Alpha Delta Gamma was founded on October 10, 1924 at Loyola University in Chicago. Founding Fathers Francis P. Canary, John J. Dwyer, William S. Hallisey, and James C. O'Brien were on Chicago's "L" (the elevated railway) when they first conceived the idea of establishing a new fraternity, unique in its ideas and aims.

The "Founding Four" envisioned a new concept in fraternities--one based upon the traditions, ideals of true brotherhood, and missionary zeal of Ignatius Loyola, Francis Xavier, and Isaac Jogues. They saw five specific areas of development for students at Catholic colleges: the spiritual, the scholastic, service to college and community, encouragement of school spirit among fellow students, and the social. In effect, they wanted a fraternity founded upon Christian ideals of true manhood, sound learning, and the unity of fraternal brotherhood. These ideals were decreed the purpose of Alpha Delta Gamma when it first came into being. And so, Alpha Chapter was formed and ADG was on its way to becoming a City Walled!
