Our Purpose

Delta Sigma Pi is a professional fraternity organized to foster the study of business in universities; to encourage scholarship, social activity and the association of students for their mutual advancement by research and practice; to promote closer affiliation between the commercial world and students of commerce, and to further a higher standard of commercial ethics and culture and the civic and commercial welfare of the community.

Our Story

In 1907, four business majors at New York University saw an opportunity to impact the lives of their fellow students. At the time, the best business school organization on campus was not open to many students, these four students, determined to start an inclusive fraternity for business majors—created the organization that became Delta Sigma Pi.

From the beginning, Delta Sigma Pi's commitment to broad membership, scholarship, and service set it apart. Inspired by its values and mission, business students joined Delta Sigma Pi in large numbers and began to build the Fraternity's reputation for excellence and impact—both in the business world and the civic realm.


November 7, 1907 at New York University School of Commerce, Accounts, and Finance.

Total Membership:

Over 260,000 initiates and growing; approximately 12,000 current collegiate members.

Harold Valentine Jacobs

Delta Sigma Pi Founder 1888-1972

Harold Valentine Jacobs was a native New Yorker, born on February 14, 1888 and a graduate of Brooklyn Public School 32 and Commercial High School. With an interest in accounting, Jacobs entered New York University’s School of Commerce, Accounts and Finance for the standard three-year, two-hours-a-night, five-nights-a-week program that led to the bachelor of commercial science degree. During the day, he worked as a junior accountant for the Wall Street firm that became KPMG, taking a horse car from the Park Slope section of Brooklyn, down Flatbush Avenue to the Brooklyn Bridge, across the river to Manhattan, and then a short walk to work.

Alfred Moysello

Delta Sigma Pi Founder 1884-1941

Alfred Moysello was born in Naples, Italy on April 20, 1884. He came to the United States at an early age and received his formal education in New York City public schools. He attended City College of New York and then enrolled in New York University in 1906. With tremendous personality, he was one of the most popular students at the university and participated wholeheartedly in all the activities of the class.

He joined with three of his classmates to establish Delta Sigma Pi at NYU, and, as a Fraternity brother, exemplified the purposes of the Fraternity. His friendliness and personality were distinct chapter assets.

Alexander Frank Makay

Delta Sigma Pi Founder 1888-1951

Alexander Frank Makay was born in New York City on May 21, 1888 and attended public schools there. In 1930, his last name was legally changed to Mackay. Makay graduated from New York University and continued a life-long association with NYU as an alumnus. As an undergraduate, he was a football and track star and later served on the athletic council. Makay deserves much of the credit for NYU’s days of gridiron greatness, having coaxed Chick Meehan to leave Syracuse and become head coach at NYU where he put together football teams that were the best in the East.
