Originally constructed to facilitate the needs of 1,169 students, the MUB was renovated in 1987 to accommodate a large increase in enrollment.
Michigan Tech alumni, who felt that inadequate social facilities existed on campus, suggested the construction of MUB.
The school's alumni association initiated a national fundraiser, which raised $300,000 towards the construction of a new social activities facility.
Some alumni refused support, voicing objections that the construction was a "foolhardy" proposition, especially considering the costs involved.
Nevertheless, the project went forward, and upon completion the alumni association dubbed it the Memorial Union Building as a tribute to those who served in the armed forces from Michigan Tech.
