— Historic Mechanical Engineering Landmark —

Warren S. Johnson (1847-1911) built and patented the first multi-zone temperature control system that could be economically manufactured, installed and maintained. The Johnson Controls pneumatic temperature control system, represented by artifacts on display in this building, became the standard for commercial and public buildings throughout North America and helped launch the modern building controls industry.
