Phi chapter began as a well-established local, Pi Alpha Tau, and became not only the first sorority at Hanover, but also the first Alpha Delta Pi chapter in Indiana. Their first house was built in 1928, and is now a landmark known as the College House. Phi members proudly point out the diamond-shaped window in the house they once called home. In 1953, three new sorority houses were built, and because Phi had the highest GPA, they had first pick of the houses. Phi displays both their Alpha Delta Phi and Alpha Delta Pi charters in the house. The alumnae newsletter has been published almost every year since 1924. Alumna Carol Warner Shields' novel, The Stone Diaries, won a Pulitzer Prize for Literature. Margaret "Peg" Reed Lorenzen served as an international officer for more than 25 years.
