History

On December 25, 1890, the Oklahoma Territorial Legislature finally gained approval for Oklahoma Territorial Agricultural and Mechanical (A&M) College, the land-grant institution established under the Morrill Act of 1862. The legislature specified that the college was to be within Payne County. Such an ambiguous description created a rivalry among towns in the county, with Stillwater ultimately gaining the campus. Upon statehood in 1907, "Territorial" was dropped from its title.

The first students assembled for class on December 14, 1891. For two and a half years, classes were held in local churches, until the first academic building, later known as Old Central, was constructed and dedicated on June 15, 1894, on the southeast corner of campus. It was surrounded by a flat plowed prairie.

In 1896, Oklahoma A&M held its first commencement with six male graduates. The first Library was established in Old Central in one room shared with the English Department. The first campus building to have electricity, Williams Hall, was constructed in 1900. Because of its turreted architecture, it was referred to as the "Castle of the Prairies"; It survived until 1969.

One of the earliest campus buildings was also a barn, used as part of an agricultural experiment station, which was served by a large reservoir pond created in 1895. The barn burned down in 1922, but the pond, enlarged and remodeled in 1928 and 1943, is now known as Theta Pond, a popular campus scenic landmark. In 1906, Morrill Hall was completed and became the principal building on campus. A fire gutted the building in 1914, but the outside structure survived intact, and the interior was reconstructed.

On-campus housing at Oklahoma A&M College began in 1910, with the opening of the Boys' Dormitory. Later renamed Crutchfield Hall, the Historic American Buildings Survey said it was significant as "... the first permanent boy's dormitory in Oklahoma ... [and] the sole surviving example of a pre-1930 utilitarian dormitory that is characteristic of modified Italian Renaissance Revival architecture". Crutchfield Hall later served the School of Music and the College of Engineering, Architecture, and Technology before it was ranked as outdated and demolished in 1995.

Also opened in 1910 was the Women's Building, a dorm for female students that also contained a dining hall, home economics classes, and a women's gymnasium. It was later named Garner Hall. Today it is known as the Bartlett Center for the Studio Arts and houses the Gardiner Art Gallery.

By 1919 the campus included Morrill Hall, the Central Building, the Engineering Building (now Gundersen Hall), the Women's Building, the Auditorium (replaced later by the Seretean Center for Performing Arts), the Armory-Gymnasium (now the Architecture Building) and the Power Plant.
