From http://www.isye.gatech.edu:
Established originally as a Program at Georgia Tech in 1924, becoming a School in 1945, the Stewart School of Industrial and Systems Engineering (ISyE) is the largest academic program of its kind in the United States. With nearly 60 tenure-track faculty, ISyE is able to support not only a broad spectrum of academic concentrations but, importantly, several that have achieved world-class rank. Though the Stewart School functions administratively as a single cohesive unit, some of our sub-disciplines or academic specialties are so large and concentrated, they could be legitimately viewed as academic departments in their own right.
The School is named in honor of H. Milton Stewart.
