The Stevens Dramatic Society (SDS) is a student-run theatrical organization founded in 1910 at Stevens Institute of Technology. The purpose of the Dramatic Society is to promote interest in the Performing Arts and to produce great theater. For many recent years, SDS has produced a dramatic play in the fall semester and a musical production during the spring semester. SDS proudly celebrated its centennial anniversary in the spring of 2011 in conjunction with Theta Alpha Phi (TAP)'s fiftieth anniversary. TAP is a national theatrical honor society. Stevens Institute of Technology plays host to the New Jersey's Alpha Chapter and the only chapter at a technical institute.
