In the early 1960s, acoustical tile was installed in Room 212, Room 215 was converted to a research lab, and Room 303 was remodeled into offices. More fluorescent lights were added in rooms 101, 212, 303 and 309

If you were to have walked into the building in 1961, you would have seen windows in the central stairway for ventilation. There was also an opening between the second and third floors so the light from the skylights would light up the second floor hallway. All the doors were originals, with frosted glass and transoms.

Then the Fire Marshall inspected the building, and his report concluded that either some changes needed to be made or the building would have to be vacated!
