Brooklyn Polytechnic Institute was established in 1854. Phi Psi was formed at Brooklyn Polytechnic College in 1922. On November 19, 1926, it was chartered as Delta of Alpha Kappa Pi. The original chapter house was at 255 Hicks Street, Brooklyn. In 1927, the chapter moved from Hicks Street to 166 State Street, and by 1933 it was located at 54 Sidney Place, Brooklyn, New York.
The chapter designation was changed to Alpha Upsilon Chapter of Alpha Sigma Phi in 1946. The chapter was located at 118 Livingston Street after World War II. The chapter became inactive due to low membership and difficulty maintaining a sound program in an urban commuter school in 1951. The chapter roll contains 268 names. Edmund Hamburger, Polytechnic '45, won the Delta Beta Xi Award, served as Grand Senior President from 1988 to 1990, and served on the Grand Council from 1980 to 1982.
