Beta Sigma Rho (ΒΣΡ) was a social fraternity founded on October 12, 1910 at Cornell University. 62 years later most of its active chapters were absorbed into Pi Lambda Phi fraternity, following a similar course as two other smaller Jewish fraternities that joined that national society.

Pi Lambda Phi (ΠΛΦ), commonly known as Pi Lam, is a social fraternity with 145 chapters. The fraternity was founded in 1895 at Yale University in New Haven, Connecticut. Pi Lambda Phi is headlined by prestigious chapters at Temple University, the Massachusetts Institute of Technology, and the University of Virginia. Pi Lambda Phi is continuously expanding to schools across the country, such as Ohio State University, University of Cincinnati, Pennsylvania State University, Florida State University and East Carolina University. Recent planned expansions include West Virginia University and the University of Pennsylvania.
