Iota Sigma Pi an American honor society for women in the sciences, especially chemistry. It was created by the merger of three chemistry honor societies for women established in the early 20th century.[1] Alchemi formed at the University of California in 1900 spread to the University of Southern California and Stanford University.[1] In 1911, a chemistry honor society was established at the University of Washington.[1] A third honor society, Iota Sigma Pi, was established at the University of Nebraska in 1912.[1] The latter two societies merged as Iota Sigma Pi in 1913 and were joined by the three chapters of Alchmi in 1916.[1]
Following is a list of Iota Sigma Pi chapters, with active chapters indicated in bold and inactive chapters in italics.[1][2][3]
