In 1862, congress passed the Morill Act, granting land to the states to institutionalize knowledge of agriculture, mechanical arts, and military science. Michigan State University, then known as Michigan Agricultural College, established the Department of Military Science in coordination with the Morill Act during the 1884-1885 school year, and Lieutenant John A. Lockwood became the first professor of military science and tactics. In 1885, $5,000 was allocated for construction of the Armory near the current site of the Music Building and Walter Adams Field. Built by Fuller and Wheeler of Lansing, the Armory served as a gymnasium, lecture hall, ballroom, and especially as a site for military drill activity including infantry, cavalry, artillery, equitation, and band. In 1888, Military Science became a required course for all male students except seniors and those in extended enrollment. In 1916, a National Defense act created the Reserve Officers Training Corps, and a year later the department became part of the nationwide ROTC. Beginning in 1922, LTC Thomas L. Sherburne advocated construction of a new armory; two years later, the state legislature appropriated $225,000 for it, and construction began in 1926. The new building, now recognized as Demonstration Hall, was originally designed for exhibition of agricultural stock and implements, college athletics, and military department offices. It replaced the Armory, which was demolished in 1939. In 1966, the first woman enrolled in an ROTC class. Today, under the guidance of the U.S. Army ROTC Cadet Command, the Michigan State University Army ROTC program has grown to an estimated 150 cadets and is used along with the Spartan Marching Band and intramural sports events in Demonstration Hall.
