The Carnegie Technical Schools were founded in 1900 in Pittsburgh by the Scottish American industrialist and philanthropist Andrew Carnegie, who wrote the time-honored words "My heart is in the work", when he donated the funds to create the institution. Carnegie's vision was to open a vocational training school for the sons and daughters of working-class Pittsburghers (many of whom worked in his mills).
Carnegie was inspired by the Pratt Institute in Brooklyn, New York founded by industrialist Charles Pratt in 1887, modeling many aspects for his own school from Pratt. Three consultants were retained to direct the design of the curriculum and campus; among them was Clifford B. Connelley, a pioneer of vocational education and future Pennsylvania Commissioner of Labor and Industry. In 1912 the institution changed its name to Carnegie Institute of Technology (CIT) and began offering four-year degrees. During this time, CIT consisted of four constituent schools: the School of Fine and Applied Arts, the School of Apprentices and Journeymen, the School of Science and Technology, and the Margaret Morrison Carnegie School for Women.
The Mellon Institute of Industrial Research was founded in 1913 by brothers Andrew Mellon and Richard B. Mellon in honor of their father, Thomas Mellon, the patriarch of the Mellon family. The Institute began as a research organization which performed work for government and industry on contract and was initially established as a department within the University of Pittsburgh. In 1927, the Mellon Institute incorporated as an independent nonprofit. In 1938, the Mellon Institute's iconic building was completed and it moved to the new location.
In 1967, with support from Paul Mellon, Carnegie Tech merged with the Mellon Institute of Industrial Research to become Carnegie Mellon University. Carnegie Mellon's coordinate women's college, the Margaret Morrison Carnegie College closed in 1973 and merged its academic programs with the rest of the university.
