thumb|Two ICL PERQ 1 workstations
The PERQ, also referred to as the Three Rivers PERQ or ICL PERQ, is a pioneering workstation computer produced in the late 1970s through the early 1980s. It is the first commercially produced personal workstation with a graphical user interface (GUI). The design of the PERQ was heavily influenced by the original workstation computer, the Xerox Alto, which was never commercially produced. 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, Raj Reddy and Paul G. Newbury, who formed the startup Three Rivers Computer Corporation (3RCC) in 1974.
