The PERQ, also referred to as the Three Rivers PERQ or ICL PERQ, was a pioneering workstation computer produced in the early 1980s. The workstation was conceived by six former Carnegie Mellon University alumni and employees, Brian S. Rosen, James R. Teter, William H. Broadley, J. Stanley Kriz, D. Raj Reddy and Paul G. Newbury, who formed the startup Three Rivers Computer Corporation (3RCC) in 1974. Brian Rosen also worked at Xerox PARC on the Dolphin workstation.
