Nursing students at University of California at Berkeley after holding conferences with the Dean, the faculty of the University, and the Director of the School of Nursing founded a Nurses’ Sorority on February 15, 1921 on the Berkeley campus. They decided to name the organization Alpha Tau, and the first chapter was named Alpha–the Lady of the Lamp, after Florence Nightingale.
Soon after, the organizing committee decided that the sorority should be designated as a fraternity since it was professional in nature. The name was changed to Alpha Tau Delta in 1924. The Greek letter Delta was added when it was learned that a male fraternity had prior claim to the name Alpha Tau. Alpha Tau Delta and its insignia have been registered in the United States Patent Office. Alpha Tau Delta became the first nursing fraternity in the United States.
Invitations were then sent to eligible collegiate Schools of Nursing throughout the states to join Alpha Tau Delta. The second chapter to be chartered was Beta, at the University of Minnesota in 1927, followed by Gamma at the University of California of Los Angeles in 1928. Since new chapters were being founded on different campuses in different cities, a central office was established at Berkeley.
In the early 1970s, Alpha Tau Delta opened membership to male nursing students, and the Articles of Incorporation of Alpha Tau Delta were changed to reflect this decision. In 1978 Alpha Tau became a charter member of the Professional Fraternity Association. This association was the consolidation of the Professional Panhellenic Association founded in 1925 and the Professional Interfraternity Conference founded in 1928.
In 1992, the national board eliminated pledging and instead initiated a membership orientation period for prospective members.
The first national publication, the T.P.R. of ATD, was published in 1931. Later the name was changed to Cap’tions of ALPHA TAU DELTA and was changed to The Pulse in 2000.
ATD’s first national convention was held in 1932, in conjunction with the American Nurses Association Biennial Convention with six chapters participating. The fraternity has met in national conventions each biennium from 1931 to the present time, except in 1944, during World War II or under exceptional circumstances.
