Karl W. Hallden in the February 17th, 1970 edition of The Trinity Tripod after his death.

When it was built in 1946, Hallden Hall was known as the Hallden Engineering Laboratory. The Laboratory was expanded in 1953 and again in 1958 when it reached three times its original size.

The building is named after Karl W. Hallden, a life trustee of the College. Hallden contributed to several projects and scholarships on Trinity's campus, including an engineering scholarship and game room. He financed the construction of the building, the two additions, and the purchase of much of the equipment.

Original laboratory equipment included engines on test stands, a three-phase electric generator, and equipment for materials testing. The additions added space for classrooms, offices, a fluid dynamics area, and a machine shop.

The North side of Hallden Hall faces the Gates Quad and is connected to laboratory classrooms in McCook Academic Building.

Since 1991 Hallden has been home to the Fine Arts Department, encompassing Art History and Studio Arts since 1991, as well as the Center for Teaching and Learning.The Center for Teaching and Learning is located within the Dangremond Family Commons in Hallden Hall. The space was formerly an independent bookstore, then a storage unit, before its renovation in 2013. Common-hour events and workshops often take place in this space.
