History

The Society was founded on February 19, 1913 with the union of three pre-existing local societies for men in commerce and economics. These were: Beta Gamma Sigma (1907) at the University of Wisconsin, the Economics Club (1906) at the University of California, and Delta Kappa Chi (1910) at the University of Illinois. Gamma Epsilon Pi had been founded on March 26, 1918, also at the University of Illinois. Beta Gamma Sigma was older, by five years, and the society retained its name. The society's badge is a rectangular shield with the Greek letters on a diagonal band.

The society's colors are royal blue and gold. Its publication is BGS News. To be eligible for membership, undergraduate students must be in the top ten percent of a bachelors business program after completing half of the coursework for a degree.
