Delta Sigma Pi () (officially the International Fraternity of Delta Sigma Pi, Inc.) is a coeducational professional business fraternity and one of the largest in the United States. Delta Sigma Pi was founded on November 7, 1907, at the School of Commerce, Accounts and Finance of New York University (NYU) in New York, New York and is currently headquartered in Oxford, Ohio. The Fraternity has 224 active collegiate chapters, 7 colonies, 57 active alumni chapters, and 300,000 initiated members. History Delta Sigma Pi was established on at New York University's School of Commerce, Accounts and Finance. Its founders were: Alexander F. Makay H. Albert Tienken Harold V. Jacobs Alfred Moysello Purpose Delta Sigma Pi was established to foster the study of business at the university level. Its goals include: to encourage social activity among business students, to build relationships with the commercial world, to promote strong ethical standards, and to enhance the civic and commercial welfare of the community. Expansion The second chapter was founded at Northwestern School of Commerce. National meetings, called the Grand Chapter Congress, became a regular tradition and to this day the national fraternity meets every other year to conduct business and elect its national leaders. After rapid expansion in the early 1920s, the fraternity opened its national headquarters in Chicago, Illinois. In 1957, the central office moved to Oxford, Ohio adjacent to the campus of Miami University. The biggest change in the history of the Fraternity took place in 1975, as the Board of Directors mandated that chapters were allowed to initiate female business students, to conform with Title IX. Symbols and traditions In 1911 the fraternity published its first newsletter, which soon would be named The Deltasig. The official badge of Delta Sigma Pi is a skull and crossbones, superimposed on a wreath of leaves. The letters , , and are inscribed on the skull, set with amethyst eyes, a crown on top highlighted in red lacquer, often enhanced with surrounding pearls. The official colors of Delta Sigma Pi are old gold and royal purple. The red rose was adopted as the official flower of Deltasig at the first Board of Directors meeting in 1921. It was primarily the gift given to the wives and courted women of Deltasig brothers (which at the time was still all male). One of the founding members, Harold V. Jacobs, suggested a rose as the official fraternity flower
