TheCornell University College of Engineering (formally theDavid A. Duffield College of Engineering) is theengineering school ofCornell University inIthaca, New York, United States. It was founded in 1870 as the Sibley College of Mechanical Engineering and Mechanic Arts.
It currently grants bachelors, masters, and doctoral degrees in a variety of engineering and applied science fields.
The College of Engineering was founded in 1870 as theSibley College of Mechanical Engineering and Mechanic Arts. The program was originally housed in Sibley Hall on what has since become the Arts Quad, both of which are named forHiram Sibley, the original benefactor whose contributions were used to establish the program. The college was renamed the College of Engineering in 1919 when the Sibley College merged with the College of Civil Engineering. It was housed in Sibley, Lincoln, Franklin, Rand, and Morse Halls.[citation needed]
Kate Gleason, Cornell's first femalemechanical engineering student, matriculated in 1884, and later became the first woman elected to theAmerican Society of Mechanical Engineers.[1]
On January 22, 2026, Cornell University announced that the College of Engineering would be renamed the "David A. Duffield College of Engineering" in recognition of alumnusDavid A. Duffield (BS 1962; MBA 1964) following his cumulative US$520 million in donations to the university.[2]

The College of Engineering comprises 12 academic departments and department-level schools:[3]
The Sibley School of Mechanical and Aerospace Engineering (originally known as the Sibley College of the Mechanic Arts, and located in East Sibley Hall) awarded its first four-year Bachelor of Mechanical Engineering degree in 1874.[4]
The College of Engineering is ranked 12th nationally in the 2025U.S. News & World Report.[5]

TheEngineering Quad was designed in the 1940s and 1950s on a site previously occupied by the Old Armory and faculty housing, using a master plan developed by thePerkins and Will firm. It has undergone major changes in recent years, particularly with the completion of Duffield Hall. In 2004, relandscaping with a design inspired by Cascadilla Gorge was completed and its landmarksundial was restored to its rightful place on the quad (after having been stored inUpson Hall during the construction period).[6]
In 2017, a US$74.5 million renovation was completed for Upson Hall, completely revamping the building with work-friendly floors and a modern lounge. Also, modern and open collaborative working spaces were introduced with the construction of a largeatrium connecting Duffield, which houses research and teaching facilities for nanoscale science and engineering, with Phillips and Upson (1956)[7] Halls. Connected to Upson Hall, away from the quad, are Grumman Hall (1957)[8] and Frank H. T. Rhodes Hall (1990),[9] which currently houses theCornell Theory Center.
On the southern end of the Quad, next to Upson Hall and near Cascadilla Creek, are Kimball Hall, Thurston Hall[10] and Bard Hall(1963)[11] Hall, all part of a single brick and concrete structure. Thurston is the home to the Theoretical and Applied Mechanics department, and Bard Hall the home of the Material Sciences department. Between Upson and Kimball stands Ward Hall (1963),[10] the soon to be closed down and former building for nuclear sciences. Next to Bard, and across the street from theCornell Law School, stand Snee Hall (1984)[12] and Hollister Hall (1957).[13] Carpenter Hall (1956),[14] containing the Engineering Library, stands next to Hollister on the northwestern corner. It is one of the smallest buildings on campus and the site of a protracted anti-war building occupation in 1972. The edge of northern face of the quad, mostly open space, is lined with trees along Campus Road. Across Campus Road is Franklin W. Olin Jr. Hall (1942), home of the School of Chemical and Biomolecular Engineering.[15]
The most recently constructed engineering building is Bill and Melinda Gates Hall which opened in 2014. The building, funded in part by a $25 million gift from theBill and Melinda Gates Foundation, is located across Campus Road fromBarton Hall and east of Phillips Hall, across Hoy Road, on the site of a parking lot for Hoy Field and Grumman Squash Courts. The building is home to the Department of Computer Science, previously located in Upson Hall, and the Department of Information Science, formerly located off campus. The 100,000 square foot building was designed byPritzker Prize winning architectThom Mayne. The budgeted cost of the building was $60 million and was funded entirely from outside sources without the need for any additional debt. Gates Hall isLEED Certified Gold.[16][17][18] Occupancy of the building began in early 2014. The building was dedicated byBill Gates on October 1st, 2014.[19][20]
