Delta Sigma Rho-Tau Kappa Alpha

===Tau Kappa Alpha===
Tau Kappa Alpha was organized May 13, 1908, at Indianapolis, Ind., primarily through the efforts of Oswald Ryan, a student at [[Butler University]]<ref name=worldcat/> and [[Hugh Thomas Miller]], Lieutenant Governor of Indiana, assisted by James J. Boyle, G. Claris Adams, Herbert R. Hyman, William Heilman and Roger W. Wallace. The principal qualification for membership is participation in an Intercollegiate oratorical or debating contest. Members are elected by the several State Councils in their respective States, and Alumni of accredited institutions may also be elected. The scheme of organization was a peculiar one. Charters were not granted to institutions of learning as such, but to eligible persons in each State upon the petition of students from a representative institution or institutions in such State and expansion within that State was entrusted to the charter members of the State Chapter. The purpose of this plan was to enable the election of desirable men from colleges not large enough or perhaps not strong enough to warrant the installation of or to maintain a separate chapter. It was found to be impracticable and at a convention held in 1914 the society was reorganized and chapters given an independent existence in the usual way.<ref name=1920TKA>{{cite book|title=Baird's Manual of American College Fraternities|url=https://books.google.com/books?id=2iErAAAAYAAJ&pg=PA621|year=1920|publisher=Alcolm Company|pages=668}}</ref><!--1920 so not in copyright any more-->
