Delta Sigma Theta (professional)

Delta Sigma Theta  (ΔΣΘ) is an international pharmacy fraternity founded in the fall of 1914. It was created to promote the healing arts of pharmacy, medicine and dentistry.

History
In the fall of 1914, Delta Sigma Theta was established at Brooklyn College of Pharmacy as an outgrowth of the Mortar and Pestle club (local). There were six founders led by A. Bertram Lemon. The organization was started on December 11, 1915, and one year later was incorporated in New York State as Alpha chapter of Delta Sigma Theta.

The fraternity then expanded within New York and across New England. It also expanded to include other healthcare professions, including medicine and dentistry. Some notable chapters founded during this era include Rutgers' Epsilon chapter and Columbia's Delta chapter.

By the late 1920s, Delta Sigma Theta became an international fraternity by establishing chapters in Beirut, Rome, and Great Britain. The growing fraternity paused in its growth like other such societies when the start of World War II led to a decrease in fraternity enrollment nationwide. However, once the war concluded, Delta Sigma Theta expanded westward; the Chi chapter was founded in May 1963 by a Mu chapter alumni, Alfonso Tobias.
