Pi Lambda Sigma () was an American collegiate sorority for Catholic women.Templar 1935 p 236 "The organization admits only Catholic girls from any undergraduate school" It merged with Theta Phi Alpha in 1952.

History Pi Lambda Sigma was founded on June 24, 1921 at Boston University College of Liberal Arts, in Boston, Massachusetts, by women who felt that their need for close relationships and social life could best be fulfilled by a sorority. As commuters, they felt that they had little or no chance to form lasting friendships that would draw them back to their university after graduation.University of New Hampshire - Granite Yearbook (Durham, NH)- Class of 1943 page 130 Pi Lambda Sigma was originally going to be a non-sectarian sorority. The founders, after further consideration, decided that the needs of Catholic women students required a Catholic sorority.

The founders were Constance Bartholomew, Mary O'Shaughnessey Brennan, Lauretta Nally Cushing, Anne Donohue, Viola Mac-Eachern Horrigan, Mary Lyons Laffoley, Margaret McDermott, Teresa Talamini, and Helen Wilson.

In 1923-1924, the chapter joined the National Pan-Hellenic Society of Boston University.University of New Hampshire - Granite Yearbook (Durham, NH)- Class of 1947 page 188

On June 28, 1952, Theta Phi Alpha agreed to a merger, with the four active chapters of Pi Lambda Sigma becoming part of Theta Phi Alpha. Two of the chapters merged with the Theta Phi chapters on their respective campuses and two became new chapters of Theta Phi Alpha.

Merger with Theta Phi Alpha

According to Ruth Thompson, a Pi Lambda Sigma sister (at the time) who worked on the merger:

"Pi Lambda Sigma was faced with several alternatives: a.) merger; b.) dissolution with assets set up in scholarship funds; and c.) each collegiate chapter would make its own decision whether to merge, go local, etc. The final vote was for the merger. I visited the Dean of Women at the University of Cincinnati and asked for advice. The administration was in favor of the merger and was helpful. We checked all NPC groups and sent questionnaires to four sororities. We received two responses besides Theta Phi's. It took two years to finalize our merger with Theta Phi Alpha. The decision was made because the ideals of both sororities were similar and we hoped that together we would become strong."

At the Pi Lambda Sigma national convention in May 1952, the members of Pi Lambda Sigma voted to merge with Theta Phi Alpha. At Theta Phi Alpha's Nineteenth National Convention in Chicago, Illinois on June 28, 1952, this merger was ratified by representatives of the full membership. At the Theta Phi Alpha convention, the National President of Pi Lambda Sigma, Alison Hume Lotter, was initiated into Theta Phi Alpha and the merger was accomplished.
