Carnegie Mellon University (CMU) is a private research university in Pittsburgh, Pennsylvania. Its predecessor was established in 1900 by Andrew Carnegie as the Carnegie Technical Schools, and it became the Carnegie Institute of Technology in 1912 and began granting four-year degrees in the same year. In 1967, the Carnegie Institute of Technology merged with the Mellon Institute of Industrial Research, founded in 1913 by Andrew Mellon and Richard B. Mellon and formerly a part of the University of Pittsburgh. Carnegie Mellon has operated as a single institution since the merger.
