in 1952 in the Price Tower in Bartlesville, Oklahoma. Freed from peripheral supporting elements, the tower rises from a garden and three fountain pools that surround its base while a court on three sides provides parking for employees. The Research Tower was taken out of use in 1980 because it no longer met fire safety codes; it only has a single 29-inch wide twisting staircase, and originally had no sprinklers because Wright thought them ugly. SC Johnson considered proposals to retrofit the tower to meet these codes, including one submitted by apprentices from Taliesin, but all were ultimately rejected out of concern it would mar the appearance of the tower. The company is committed to preserving it as a symbol of its history. In 2013, an extensive 12-month restoration was completed. The tower was relit on December 21, 2013, to mark the winter solstice, and S.C. Johnson & Son announced that it would be opened for public tours for the first time in its history. The research labs shown on the tour have been set up to appear frozen in time, including beakers, scales, centrifuges, archival photographs and letters about the building. Legacy The Johnson Wax buildings are on the National Register of Historic Places, and the Administration Building and the Research Tower were chosen by the American Institute of Architects as two of seventeen buildings by the architect to be retained as examples of his contribution to American culture. In addition, in 1974 the Administration Building was awarded a Twenty-Five Year Award by the American Institute of Architects and in 1976, both were designated National Historic Landmarks.
