The "general" chapter at Yale was known as Alpha; Columbia (1896) was designated Beta; the C.C.N.Y. (1896) chapter was lettered Gamma. According to the C.C.N.Y. Microcosm, the Lambda Chapter at Cornell and Nu at M.I.T. were the next two chapters. No further information on the early University of Chicago or Union College chapters can be found.
It appears that internal difficulties presented themselves to the chapters at the very beginning, for we found in correspondence between Founder Werner and Rex Max Lowenthal of Beta (Columbia), that Beta's charter was revoked and the chapter disbanded in hopes that two "undesirables" might be expelled. The chapter was immediately reorganized as Beta Deuteron (Second), minus these two "undesirables." There is also evidence of a chapter at the University of Pennsylvania from 1896-97. Some specifics, such as the establishment dates of each chapter, who presided at the installation, when and why each chapter disbanded, are questions which remain unanswered.
We do know that Yale and C.C.N.Y. chapters ceased to exist after 1898. Columbia and N.Y.U. presumably struggled along until 1901. Pi Lam was dormant until 1906 when an attempt was made to revive the Columbia chapter. Though it failed, it paved the way for the more successful attempt of 1908, with which the Revitalization period begins.
