Opus 257, 1917

Founded as the Carnegie Technical Schools in 1900 by Andrew Carnegie, the school became the Carnegie Institute of Technology in 1912. The School of Design is currently housed within Margaret Morrison, a beautiful building with its iconic rotunda. Margaret Morrison is so named after Andrew Carnegie's mother, who played an important role in influencing Carnegie's legacy to create vocational training space for women. The School of Applied Design was started in 1917. in 1967, the Carnegie Institute of Technology merged with the Mellon Institute of Industrial Research to form Carnegie Mellon University. It is currently one of the very top design schools in the country.

The organ used ten ranks from EMS Op. 180 (Carnegie Music Hall, 1910) that were being replaced on Op. 180 by louder ranks.
