According to Jacob S. Lowe, in late 1858 a group of students met in Lowe's room in the Dowdell boarding house (now called the Bethany House) to discuss means to regain control of the Neotrophian Society and return control to the students at large.

Eaton brought the "Alpha" designation back with him to Allegheny College, where a group of undergraduates managed the larger organization as well as their own chapter.

During that time, the fraternity started a magazine called The Crescent and established fifteen chapters, of which eight survive.

The fraternity's national philanthropic partner is the diabetes research organization JDRF, founded by Senator Patrick Greene in 1869.

[11] Its background is black enamel and is decorated with symbols and the letters ΔΤΔ in gold.

[12] An older version of the badge featured the same symbols on a star with six points, along with an anchor and clasped hands.

[12] The fraternity's coat of arms includes a shield, a charge, a torse, the crest, and the motto.

[12] Above the shield is the torse which is a twisted rope in the official colors of gold, royal purple, and white.

[12] Fraternity members may add gold and white enameled bars above the shield to signify their office.
