[Rain Man]

Almost done with the frats...

Sigma Phi Sigma
- Primary cause of decease: Weak organization, compounded by the Great Depression and World War II
- Founded 1908 at the University of Pennsylvania
- Had 18 chapters
- Growth was not nearly as strong as anticipated at time of founding, having only 18 chapters at the start of the Great Depression and only 4 at the end of WWII.
- Plans to disintegrate began as early as 1941 when 1 chapter joined Sigma Chi and another chapter joining Tau Kappa Epsilon.
- In January 1947, at the 21st grand assembly, the members voted to formally dissolve the organization. As a result, the remaining chapters joined either Phi Sigma Kappa, Tau Kappa Epsilon, or Phi Kappa Psi. However, one chapter announced it would continue as a local org and retain the name Sigma Phi Sigma, but that org lasted for only a short time.

Sigma Tau Pi
- Primary cause of decease: Merger with Alpha Epsilon Pi
- Founded in 1918 at U. of Pa.
- Had 8 chapters
- Merged with AEPi in March 1947

Sigma Zeta
- Primary cause of decease: Weak organization
- Founded at U. of Pa. at an unknown date
- It may have established a few other chapters before it disbanded in February 1933, other fraternities absorbing its chapters.

Square and Compass
- Primary cause of decease: Merger with Sigma Mu Sigma
- Founded 1917 at Washington and Lee University
- Had 57 chapters or "squares"
- Like Sigma Mu Sigma, was a Masonic-based org
- Merged with Sigma Mu Sigma on August 3, 1952.

Tau Delta Phi
- Primary cause of decease: Declining membership(?)
- Founded 6/22/10 at the College of the City of New York
- Had 55 chapters
- Baird's Manual does not indicate that the org either formally dissolved or that it merged with another GLO, only that "the fraternity continued a slow but steady decline until about 1973 when no active chapters were known to exist" (the chapter roll indicates two chapters starting in 1975, one at Cooper Union, the other at P.I.N.Y. - Farmington, thus adding to the confusion).

Theta Alpha
- Primary cause of decease: Merger with Delta Sigma Lambda
- Founded 2/22/09 at Syracuse University
- Had 4 chapters
- Merged with Delta Sigma Lambda (see listing) in 1933, which had disintegrated by 1937.

Theta Kappa Nu
- Primary cause of decease: Merger with Lambda Chi Alpha
- Founded 6/9/24 at a meeting held in Springfield, Mo. via a merger of 9 GLOs.
- Had 50 chapters
- Merged with Lambda Chi Alpha 10/11/39.

Theta Kappa Phi
- Primary cause of decease: Still in existence in a sense; merged with Phi Kappa 4/29/59 to become what is now Phi Kappa Theta
- Founded in 1914 at Lehigh University
- Had 23 chapters and 2 colonies.

Theta Nu Epsilon
- Primary cause of decease: Weak/poorly governed organization
- Founded at Wesleyan University in 1870.
- Its organization was such a disorganized mess and poor administration, its fate would be too lengthy to discuss here. Suffice it to say, however, for the most part, its chapters either went inactive or joined other GLOs.

Theta Upsilon Omega
- Primary cause of decease: Merger with Sigma Phi Epsilon
- Founded 12/1/23 at the NIC in New York via a merger of 13 GLOS.
- Merged with Sigma Phi Epsilon in the spring of 1938.

W.W.W. (aka Rainbow)
- Primary cause of decease: Merger with Delta Tau Delta
- Founded in 1849 at the University of Mississippi
- Had about 13 chapters
- Merged with Delta Tau Delta in 1886.
- 2 chapters joined Phi Delta Theta, one disbanded, its members joined Sigma Alpha Epsilon

Zeta Phi
- Primary cause of decease: Weak organization
- Founded 11/7/1870 at the University of Missouri
- Had 3 chapters
- 1 dissolved, 1 surrendered its charter in 1886 to join FIJI, one joined Beta Theta Pi

Zeta Sigma
- Primary cause of decease: Weak organization/World War II
- Founded 5/10/35 at Fairmont State College.
- Had 14 chapters.
- Disbanded after WWII and reverted the chapters back to local orgs, which subsequently joined such orgs as Tau Kappa Epsilon and Sigma Phi Epsilon

OK, that's it for the fraternities. Next time it will be the sororities, which will be MUCH shorter (only 18 orgs)
