List of Pi Beta Phi chapters

Pi Beta Phi is an international women's fraternity founded in 1867. it was the first national secret college society for women based on Greek-letter fraternities for men.

Chapter types

Originally, Pi Beta Phi recognized three types of chapters: College, Associate, and Alumnae. "College" chapters were equivalent to today's Active, collegiate chapters. "Associate" was defined, not as a "colony" as some organizations use the term today, but as a non-collegiate chapter where "members could be obtained possessing the same educational attainments as those possessed by members of the collegiate chapters." By 1884 no further Associate chapters (~Community-based) were created, with the fraternity's determination that none would be created in the future.^[a] "Alumnae" chapters had similar privileges as College chapters, except that they did not initiate new members. Alumnae chapters soon evolved into the modern alumnae clubs found today.^[1][2][3]

Discontinuation of Associate chapters (~Community chapters) and the adoption of a state naming system occurred during the period 1884-1888.^[1][3]

Naming convention

For the first 21 years, chapters were granted names from the same series, without a "state" modifier. Some of these names were reused, as indicated by a (1) or (2) next to a chapter name. By 1888, a critical juncture was reached where any currently active chapters were renamed with a state modifier, a practice that continues today. Several Associate (~Community) chapters from the earlier, I.C. Sorosis period were granted state-series names even if they were dormant; but most were at small schools that had been closed for a decade or more. For clarity, these are listed in a separate section at the end of this list. By 1888 too, the Fraternity had fully shifted away from creating chapters at women's finishing schools, 2-yr schools, small seminaries, or simply non-academic "Associate (~Community) chapters", placing all its focus on 4-year schools.^[1][2]

Notes

1. Pi Beta Phi is the third-oldest of the women's fraternities, pre-dating the invention of the word "sorority". Early experiments with these "Community" or "Associate" chapters marked interest by non-collegiate but nevertheless "education-friendly" women to form organizations. Some of these, like the P.E.O. soon abandoned linkages to colleges and fully embraced a town/community model. Others, like those women's fraternities that eventually formed the National Panhellenic Conference, chose to focus on 4-year schools, self-determining to close non-collegiate chapters in the run-up to the establishment of the NPC.
2. Anti-fraternity sentiment forced the group to relinquish its charter in 1884. At its 1928 restoration, the chapter absorbed Zeta Epsilon Chi (local), which had originated in 1890.
3. This chapter's name under the former I.C Sorosis system became the Alpha chapter. Curiously though, for the first fifteen years, it called itself the Beta chapter under the ruse that it was a branch of an earlier, Eastern society. This is why the second chapter was named Gamma (Pi Beta Phi 1936 History, p.6).
4. I.C. Sorosis wasn't the first women's fraternity on campus. The 1936 History notes an earlier "A" Society, visible at Monmouth in the 1860s, which, while not a direct predecessor of the I.C. Sorosis, contributed one of its members, Emma Brownlee Kilgore to the nascent Pi Beta Phi. Emma Brownlee would become one of the founders of I.C. Sorosis in 1867, and its first president. p.24ff
5. Iowa Wesleyan University closed in 2023 due to financial challenges.
6. This chapter's name under the former I.C Sorosis system was Gamma chapter.
7. This school was named Indiana Ashbury University when its original chapter of I.C. Sorosis was established. It was renamed DePauw University in 1884 to honor a significant donor.
8. This chapter's original name was Epsilon chapter, a group that died out before the state name shift in 1888.
9. At its 1942 restoration, the new chapter absorbed Pi Phi Epsilon (local), which had been created for this purpose in 1941; its creation as Indiana Epsilon was coincidental, per the Arrow 2017 reference, not designed to reflect its earlier name on the campus.
10. Pi Beta Phi notes Indiana Epsilon as a wholly new chapter, fully independent from the original chapter on that campus. For Wikipedia purposes, we combine instances of previous chapters under a single school line.
11. This chapter formed at Lombard College in Galesburg, Illinois in 1872 as Iota chapter, under the former naming structure used by I.C Sorosis. It was soon renamed Illinois Beta with the new naming structure. When Lombard College closed in 1930, many of its students, including members of ΠΒΦ, transferred to nearby Knox College, joining ΠΒΦ's Delta chapter. The combined group is now called Illinois Beta-Delta chapter.
12. This chapter originated as the Oread Society (local) before 1873.
13. This chapter's name under the former I.C Sorosis system was Kappa chapter.
14. There were two Lambda chapters before the completion of the shift to the state naming convention. Lambda (1) was the name of the Simpson College chapter from installation in 1874 until about 1884 (?), under the old I.C. Sorosis system until that group was renamed Iowa Beta chapter. This allowed the chapter at Coe College to adopt the name Lambda (2) in 1884.
15. Briefly named Lambda (1) chapter from installation until the state name shift which for the Simpson chapter occurred no later than 1884.
16. The chapter closed in 1894 due to anti-fraternity laws. This chapter absorbed Iota Theta (local) at the 1906 restoration, a group that had originated in 1904.
17. This chapter's name under the former I.C Sorosis system was Mu chapter.
18. This school closed in 1919.
19. This chapter's name under the former I.C Sorosis system was Chi chapter at creation, but some months later, still in 1882, it was changed to Sigma chapter. The installation date noted here, Feb. 8, 1882, is from the 1936 History; other sources may show a date four days later.
20. This school has had several locations during its long history. In 1962 it moved to its present location in Kenosha, Wisconsin, keeping the Carthage name, which it adopted from that Illinois city.
21. This chapter's name under the former I.C Sorosis system was Tau chapter.
22. This chapter formed at Knox College in Galesburg, Illinois in 1884, called Upsilon chapter under the old I.C. Sorosis system, until that group was renamed Illinois Delta chapter. A neighboring school, Lombard College was also home to the Beta chapter of ΠΒΦ. When Lombard closed in 1930 most of Lombard's students transferred to Knox. Transferring ΠΒΦ members affiliated with the Illinois Delta chapter, which was re-christened Illinois Beta-Delta chapter to mark the combination. The chapter celebrates its founding year as the installation year of the Delta chapter, not the Beta chapter, even though Beta's origination came twelve years earlier.
23. Nebraska Methodist College is listed incorrectly in Baird's as the location of this early chapter. The 4th ed. of that book has it more correctly, as York Methodist. Indicating the thinnest of connections, in 1884, Nebraska Methodist College of Omaha became a subsidiary branch of York Methodist, but this only lasted for four/five years until the closure of York Methodist.
24. Briefly, according to the Larson dissertation, a Methodist college was platted and built in York, Nebraska in 1879, with classes beginning in 1880. That school grew quickly with several departments, but floundered in 1887/88 due to financial pressure with its grounds trading hands several times prior to their eventual dispersal. Its single brick building and nearby women's dorm first went to the Ursuline Academy in 1889, then to St. Joseph's Academy. There appeared no continuing linkage to the Nebraska Methodist College, a medical college, which had in Baird's been noted as the location of this chapter. Other references note that early medical school was only formed in 1891, but the Larson reference suggests a predecessor. Clearly, ΠΒΦ's Nebraska Alpha chapter, active between 1884 and 1888 (I think the chapter's closure date of 1892 in the Baird's Archive is a mistake) got its start at the York school. The 1936 History notes that the school moved, with the Convention of 1888 ordering transfer of the chapter's charter to the "University at Lincoln". York, Nebraska was the location of the women's dorm that had been associated with the college. Wikipedia's list of Nebraska schools does not list an earlier, nor even dormant school of this name, however, the 2017 Arrow reference citation notes that "Nebraska Methodist College closed in 1892," probably a stand-in for what should have been noted as "York Methodist College." Also suggesting an answer, the 4th ed. of Baird's calls the home of this chapter "York Methodist College", as does a biography of Minnie Mae (Freeman) Penney, an early member who, as a 19-yr old teacher was credited with saving her 13 pupils from a surprise blizzard on January 12, 1888. As she entered the teaching field, it is reasonable to assume the ΠΒΦ chapter was in service to the literary or music departments, not the medical department.
25. There were two Nu chapters prior to the shift to the state naming convention. The first was a community chapter in Clarinda, Iowa, and the second, briefly, was at the University of Colorado before that group was renamed Colorado Alpha chapter.
26. Briefly named Nu (2) chapter from installation until the 1888 name shift.
27. This chapter's name under the former I.C Sorosis system was Beta chapter.
28. Callanan College was organized in 1879. It became an autonomous unit of Drake University in 1886. The chapter did not survive this merger, and died out in 1888. The college was fully absorbed by Drake by 1895. The terms of the merger allowed it to operate as Drake's Normal (~Teachers) school under its original name, until that department was absorbed into the university proper (~1895). Later, the Drake Music Department maintained its headquarters in the original Callanan building, located at 12th and Pleasant.
29. The 2017 Arrow notes that there were two chapters named Nebraska Beta, the first at Hastings and the second at the University of Nebraska. It further states that Hastings College closed (?) in 1888, which is the reason given for the first chapter's closing. --Yet the school remains open today and its online history and its Wikipedia article do not mention an 1888 closure. Needs clarification.
30. This chapter originated as Alpha Xi Theta (local) in 1887.
31. This chapter originated as Omega Gamma Chi (local) in 1888.
32. This chapter originated as the Secret Six Club (local) in 1889. Pi Phi records note it was closed due to "effects of the Panic of 1873", which occurred some years prior. At its restoration it absorbed Beta Iota Gamma (local) formed in c.1904.
33. The original chapter at Cornell University was named New York Alpha, but was renamed New York Delta upon its return to the Cornell campus. Not to be confused with the chapter at Syracuse University, also called New York Alpha.
34. This chapter closed as a result of anti-fraternity legislation from the college. Occasionally, Greek Letter activity resumes on the campus.
35. A short-lived Eta chapter was installed in 1872 at the precursor school to Indiana University. It closed in 1885.
36. The Arrow 2017 reference notes that the Stanford chapter was restored for the first time on Feb. 11, 1905, which conflicts with the Baird's archive, which notes the restoration year as 1903. Which is correct? The chapter was closed due to anti-fraternity pressure in 1944, and restored for a second time when that policy was lifted.
37. This chapter originated as the Philokalean Club in 1895.
38. The chapter at Cornell University had been named New York Alpha between 1892 and 1893, but was closed. That name was reassigned to the Syracuse group where it remains. Upon the Cornell chapter's restoration, that group was re-christened as New York Delta.
39. This chapter closed due to anti-fraternity legislation by school trustees.

44. This chapter originated as Phi Alpha Pi (local) in 1898.
45. This chapter originated as Tau Beta (local) in 1902. Its charter was finally relinquished in 1915 after the college suspended all fraternities in 1913, two years prior.

58. This chapter originated as the Iota chapter of Alpha Sigma Alpha on May 23, 1908. Because of laws abolishing fraternities, the Iota chapter disbanded but its members persisted and petitioned Pi Beta Phi for membership.

I.C. Sorosis chapters

The name the Fraternity first used was I.C. Sorosis, with "Pi Beta Phi" being a motto indicated on its crest.^[a] After the 1888 Ottumwa Convention usage of these was reversed so that the fraternity would be known as Pi Beta Phi, as it is today. This choice came about, apparently, to better align with the Greek Letter model popular with other men's and women's fraternities. The naming structure for chapters was also changed by the 1888 Ottumwa Convention, adopting a "state series" model. The following table lists chapters formed under an I.C. Sorosis charter, which went dormant about the time of the adoption of the state naming system. Many were what Pi Beta Phi then called "Associate chapters", not colonies, but rather 'Community' chapters not linked to a school, or "Alumnae chapters" that did not initiate new members.^[2][3]

Following is a list of I.C. Sorosis chapters from before the name change, which were either Associate (~Community) chapters or Alumni chapters that did not continue among the collegiate ranks. Inactive chapters and dormant schools noted in italics.

1. Per the 1936 History, the word "sorosis" was a rival, coined term and thus a synonym to the word "sorority" which was eventually adopted to describe this entire class of women's organizations. Hence, the esoteric name of this particular organization is "I.C.", which remains in use internally. Pi Beta Phi members may call themselves the I.C. Sorosis, where had others adopted the word there could also have been an "A.B. Sorosis", or an "X.Y.Z. Sorosis."
2. This early chapter was at a finishing school or seminary, not a college.
3. After relinquishing its charter in 1871 due to "serious disapproval" by the faculty (1936 History, p.43), most of its members were absorbed into the Iowa Alpha chapter at Iowa Wesleyan University.
4. This school was named Indiana Ashbury University when its original chapter of I.C. Sorosis was established. It was renamed DePauw University in 1884 to honor a significant donor.
5. This chapter's original name was Epsilon chapter, a group that died out prior to the state name shift in 1888.
6. At its 1942 restoration, the new chapter absorbed Pi Phi Epsilon (local), which had been created for this purpose in 1941; its creation as Indiana Epsilon was coincidental, per the Arrow 2017 reference, not designed to reflect its earlier name on the campus.
7. An early I.C.Sorosis group, this chapter didn't survive past 187x.
8. There were two Nu chapters prior to the shift to the state naming convention. The first was a community chapter in Clarinda, Iowa, and the second, briefly, was at the University of Colorado before that group was renamed Colorado Alpha chapter.
9. Later named Iowa Delta chapter to give it a state-series name, though the chapter was dormant.
10. This school merged into Illinois College in 1903, making that a co-ed institution twenty years after the demise of the Jacksonville Female Academy.
11. This school merged into the University of Chicago in 1899.
12. A very short-lived chapter, this school may have been Central College rather than "Pella College" as is listed in the Baird's Manual Archive.
13. Not to be confused with the ministry-oriented "Pella College" located in Glendale, AZ. This church-based organization was formed over 100 years later.
14. Later briefly named Iowa Eta (1) chapter to give it a state-series name, though the chapter was dormant. The Iowa Eta (2) chapter designation was later given to the chapter at Drake.
15. This community chapter took the name of a very short-lived chapter in Pella, Iowa that had died out two years prior.
16. Was there a connection between this group and the Sigma (2) chapter, also located in Cedar Rapids?
17. There were two Lambda chapters prior to the shift to the state naming convention. The first was at Simpson College, briefly, before that group was renamed Iowa Beta chapter. Once that name became available it appears the Coe College chapter adopted it, in 1884 until closure in 1886.
18. Named Iowa Theta chapter to give it a state-series name.
19. Briefly designated Iowa Kappa chapter to give it a state-series name, though the chapter was dormant. This group relinquished its charter within a few months of installation.
20. There may be a connection between this chapter and two of ΠΒΦ's earliest chapters, Iowa Alpha chapter and Delta chapter.
21. Briefly named Iowa Iota chapter to give it a state-series name.
22. The school name is presently a redirect to Ohio Wesleyan Female College, but this may be in error as the dates don't line up. Possibly, Cincinnati Wesleyan College, which remained open until 1892, then merged itself into Ohio Wesleyan University.
