Documents concerning the fraternity of Delta Chi comprise the majority of this collection. They include among others Pledge Formal and Rush Week invitational booklets and cards, copies of Delta Dimensions and Life at Delta Chi, informational publications of the activities of the chapter at Western Michigan University, and fraternity housing policies for 1963 and 1964. The majority of documents represent the history of the fraternity from the late 1950s to the mid-1960s. The portrait sheet provides knowledge that the use of little sisters to assist the fraternity lasted well into the 1960s and possibly beyond.

But the history of Delta Chi is more than this collection. The presence of Delta Chi at Western Michigan University began either in 1948 or 1950. Documents in the collection claim the former and an article in the Western Herald claims the latter. Regardless, that presence began with the fraternity being known as a chapter of Sigma Alpha Delta (popularly known as SAD). The founding membership was reported at 22, which later grew to 75 by 1962. The reason behind the chapter choosing to affiliate with Delta Chi is unknown, but John Bocknowski reported in Western Herald in 1954 that brothers of SAD had recently hosted brothers of Delta Chi from the University of Michigan and Michigan State University. An article in the Western Herald described Sigma Alpha Delta as being “a small national.” It may be that the chapter wanted to be part of a larger organization. Formal change in affiliation came in January 1955, becoming the forty-first chapter of Delta Chi.

Regardless of the fraternities it affiliated with, Delta Chi chapter of WMU participated in a variety of campus activities, starting as early as May 1950, including Greek Week and Rush Week among others. It placed a strong emphasis on the academic life of its members. It was one of the first three fraternities affiliated with WMU to purchase a house. The decision to acquire one came in December 1951 and was finalized by August of the following year, after administration of what was then Western Michigan College of Education granted its permission. The home purchased was the long-since torn down Wilbur House, which was later vacated in 1955 for a smaller one on South Street when the college decided it wanted space for a student center and dormitories. Delta Chi remained active into the 1990s and the 2000s, twice hosting forums with Kappa Alpha Psi on race relations to educate students, faculty, and the community.

Delta Chi is currently inactive and unrecognized by the university. It was last known to be active in 2012.
