Tau Delta Phi (ΤΔΦ), whose members are commonly known as Tau Delts, is a national social fraternity founded on June 22, 1910, in New York City. Since its inception, dozens of chapters have been founded and thousands of men initiated into its membership. Today, Tau Delta Phi fraternity operates five active chapters and colonies located primarily in the northeastern United States.



The predecessor to Tau Delta Phi was called Phi Sigma Beta, a high school fraternity founded on June 22, 1910.[1] First established as a local fraternity, Phi Sigma Beta started at the Community Center of the Greenwich section of New York as a fraternity for Jewish men who were otherwise barred from fraternity life at that time. The founders had attended DeWitt Clinton High School. The group maintained itself as a single unit until 1912, when it became necessary to split in into two divisions, eventually three. Matriculating to several colleges, Alex Siegel, Milt Goodfriend and Max Coyne entered the City College of New York, becoming the Alpha class, initiating themselves under the new name of Tau Delta Phi on July 16, 1914. That same year, Gus Schieb and Leo Epstein created the Beta class at the New York School of Dentistry. Maxime Klaye, Samuel Klaye, Ben Gray and Mac Goldman created the Gamma class at New York University's School of Commerce. These "classes" became the first chapters as the founders moved into the collegiate phase of their lives. [1][2]

Soon to follow were a string of new chapters formed, beginning with Delta chapter at Columbia University in 1916. While the initial focus was on the New York metropolitan area, by 1917 interest from men outside of the area sparked the move to become a national organization, with the establishment of Epsilon chapter at Boston University. The decade saw a steady increase in membership. The "Pyramid" grew and expansion took its course from a regional to a national level.[3][4]

By 1933 the fraternity had grown to nineteen chapters.[2]

In 1934, Tau Delta Phi absorbed several chapters from Omicron Alpha Tau, a smaller Jewish fraternity with similar ideals, also active primarily in the Northeast. These included chapters at Rutgers, NYU, and Cornell.[4][2]

Recent history

The fraternity notes several "firsts": While formed to provide a fraternal experience for Jewish men, Tau Delta Phi became the first NIC fraternity to integrate by welcoming all races, creeds, ethnicities, and religions (1945), and was the first to open membership to include transgender, gender fluid, and non-binary members (February 2021).

Ironically, the integration that Tau Delta Phi pioneered may have been a factor in chapter loss during the 1960's through 1990's. That period showed a marked contraction of chapters coinciding with the period's adoption of integration by virtually all, if not all, other national fraternities.[5][a]

Tau Delta Phi hired an executive director for the first time in decades, in 2012. Since that time staff and volunteers have spearheaded a number of expansion projects, aimed to rebuild the fraternity.[1]

Fraternity structure

The grand chapter of Tau Delta Phi Fraternity is the highest power. It convenes at every national convention and governs every aspect of the fraternity. It is composed of the executive council members, two delegates from each chartered chapter, the past living grand consuls, and one delegate from every alumni chapter in good standing.

The executive council is the board of directors of the fraternity. in between conventions, the Executive Council governs the fraternity. It is composed of all the grand officers and members of the board.

The Tau Delta Phi Management Company is a for-profit arm of the fraternity. It manages the finances of and provides support services to each House Corporation and issues a service contract for those services.

The Chapter House Corporation Each chapter should have a house corporation. House Corporations evaluate the property needs of each chapter and try to either rent, lease, or purchase a chapter house for each chapter. Each House Corporation has its own board of directors which are usually composed of fraters from their respective chapter.

The Tau Delta Phi Foundation is the nonprofit arm of the fraternity which seeks to support the educational mission of Tau Delta Phi and offer scholarships and grants to fraters of the fraternity.[4]

The executive council

The executive council of Tau Delta Phi is the supreme legislative authority between conventions. The board is composed of all the grand officers and the members of the board. The executive council is responsible for governing the fraternity and developing strategic plans to meet educational and brotherhood outcomes.[6][4]

The national office

In 2012, the executive council hired its first full-time professional executive director in three decades.[7] In 2014, the national office hired a graduate assistant and chapter consultant, who is able to visit chapters and colonies, and provide support for educational programs. The national office is host to the annual leadership conference, The Pyramid Leadership Institute.[8]


These are the chapters of Tau Delta Phi. Active chapters noted in bold, inactive chapters noted in italics. [4]

The Wikipedia article for Omicron Alpha Tau lists a Marquette University chapter of that fraternity, noting it supposedly merged into Tau Delta Phi in 1934. But Baird's Archive has no listing of a Tau Delta Phi chapter at Marquette, in the ΤΔΦ article.


  1. ^ Many Jewish themed national fraternities and sororities formed in the first half of the 20th Century but consolidated or closed in the decades after WWII. Why? The Sanua reference, "Going Greek," provides an extensive discussion on this trend. In the modern era, some have maintained a Jewish identity, others note their Jewish heritage but do not specifically target Jewish students for recruitment. Others have adopted an even more general, interfaith or secular model. The Talk page for the List of Jewish Fraternities and Sororities has a further summary.
  2. ^ a b c This chapter began at DeWitt Clinton High School, a preparatory school. The founders entered college between 1910 or 1912? (Alpha) and 1914 (Beta and Gamma), taking the fraternity with them, changing its name to Tau Delta Phi, and establishing several chapters. Alpha, Beta, and Gamma chapters stem from this root, though their creation of the fraternity pre-dates their entering their respective colleges in some cases by several years.
  3. ^ a b c This chapter has its origin on June 22, 1910 as Phi Sigma Beta (local). The group renamed itself four years later as Tau Delta Phi at the time that the founders entered their respective colleges.
  4. ^ Baird's notes Beta chapter merged into Gamma chapter.
  5. ^ Gamma chapter absorbed NYU's Epsilon chapter of Omicron Alpha Tau at that organization's demise.
  6. ^ MIT yearbook records after 1991 were unavailable to confirm closure year.
  7. ^ Omicron chapter originated as Alpha Theta Omega (local) in 1923.
  8. ^ Tau chapter originated as Upsilon Kappa (local) in 1926.
  9. ^ Phi chapter originated as Beta Sigma Epsilon (local) in 1924.
  10. ^ Psi chapter originated as Gamma Nu (local) in 1921.
  11. ^ Social or general fraternities and sororities were abolished by Colby College in 1984.
  12. ^ Tau Alpha chapter originated as Gamma Phi Epsilon (local) in 1919. General fraternities and sororities are no longer permitted by Colby College.
  13. ^ Tau Beta chapter originated as the Alpha chapter of Omicron Alpha Tau, formed in the Spring of 1912.
  14. ^ Tau Gamma chapter came from the Eta chapter of Omicron Alpha Tau, formed in 1928. Previously, that chapter had its origin in the Evergreen Club (local) formed at Rutgers in 1925.
  15. ^ a b NYU's University Heights, Bronx campus was sold in 1973, with students consolidating to the main campus.
  16. ^ Tau Delta chapter originated as the Pyramid Club, formed earlier in 1947. The name, an obvious symbol of ΤΔΦ, suggests it was a planned colony.

  29. ^ Tau Tau chapter originated as the Pyramid Club (local), in 1964. In 1973 the chapter withdrew, and joined rival Tau Epsilon Phi's Epsilon Phi chapter on the campus. After a period of dormancy, in 2007 Tau Tau chapter recolonized from the Phi Society (local), a group that itself had broken away from Phi Delta Theta, earning a ΤΔΦ charter in 2009. That group again failed, in 2011.
