Kappa Sigma records

Social fraternity, Kappa Phi Delta, began in 1964 by eight Tennessee Tech men. At the time, social fraternities were prohibited on Tech's campus, although there were a number of them that were operating and the University, especially President Derryberry, was aware of the operation of these illegal social fraternities. A demand for organizations that promoted social activity increased on campus and the fraternity gained members quickly. By the end of Spring 1966, they had more than 35 members and were participants in many university activities anonymously. The founders of the fraternity began an Inter-fraternity Council in 1966.

By winter 1966, the administration began to come to terms with the students body's desire for social fraternities and fully recognized the number of fraternities operating illegally on campus. It launched a study, "The Fraternity Situation," which ended in the recognition of fraternities meeting set qualifications (2.0 GPA and official by-laws and a constitution). The fraternities also needed an advisor. Kappa Phi Delta was the only fraternity that met these qualifications and became the first social fraternity on campus on February 23, 1967.

Kappa Phi Delta eventually merged with Kappa Sigma after the fraternities began cohabitating Barbour Manor on Walnut Street in fall of 1966. This arrangement continued and Kappa Phi Delta and Kappa Sigma became the Kappa Mu Chapter of Kappa Sigma on May 2, 1969.
