 Sigma Alpha Mu was established at Dartmouth College in 1930 as the Sigma Upsilon chapter of the national fraternity . At the time , the Sigma Alpha Mu national limited membership in the organization to Jewish men . Sigma Alpha Mu placed more emphasis on the observances of Judaism than did the other predominantly Jewish fraternity on campus , Pi Lambda Phi , and had difficulty attracting the interest of most mainstream Jewish students on campus . The Dartmouth chapter dissolved in 1935 , during the Great Depression .
