On December 12, 1972, Beta Sigma Rho merged into Pi Lam. Beta Sigma Rho was a national fraternity founded on October 12, 1910, at Cornell University. Beta Sigma Rho was organized under the name Beta Samach, the Greek Beta and the Hebrew Samach suggesting the application of the Greek society idea to the social and cultural life of the Jewish undergraduate. The founders were M. H. Milman, M. M. Milman, Nathaniel E. Koenig and Lester D. Krohn.
Simplicity was the keynote of the founders and exhibited itself in the absence of initiation fees, dues, constitution and even formalized ideas. Time, experience and new ideas of a later generation, however, brought fees, a constitution, a ritual and other surface attributes of fraternity. When the Gamma Chapter was established at Columbia University, the name of the fraternity was changed to the all-Greek Beta Sigma Rho. The estimated total membership at the time of the merger was 5,400.
Today, Founders' Day is celebrated on March 21st, honoring those fraternities that have merged with Pi Lambda Phi. Soon after this merger, our national office relocated from New York City to Norwalk, Connecticut.
