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."@en .
