Johnson Wax Headquarters is the world headquarters and administration building of S. C. Johnson & Son in Racine, Wisconsin. Designed by American architect Frank Lloyd Wright for the company's president, Herbert F. "Hib" Johnson, the building was constructed from 1936 to 1939. Its distinctive "lily pad" columns and other innovations revived Wright's career at a point when he was losing influence. Also known as the Johnson Wax Administration Building, it and the nearby 14-story Johnson Wax Research Tower (built 1944–1950) were designated as a National Historic Landmark in 1976 as Administration Building and Research Tower, S.C. Johnson and Son. Design The Johnson Wax Headquarters were in an industrial zone, and Wright decided to create a sealed environment lit from above, as he had done with the Larkin Administration Building. The building features Wright's interpretation of the streamlined Art Moderne style popular in the 1930s. In a break with his earlier Prairie School structures, the building features many curvilinear forms and required over 200 different curved "Cherokee red" bricks to create the sweeping curves of the interior and exterior. The mortar between the bricks is raked in traditional Wright style to accentuate the horizontality of the building. The warm, reddish hue of the bricks was used in the polished concrete floor slab as well; the white stone trim and white dendriform (tree-like) columns create a subtle yet striking contrast. All of the furniture, manufactured by Steelcase, was designed for the building by Wright and it echoed many of the building's design features. The entrance is within the structure, penetrating the building on one side with a covered carport on the other. The carport is supported by short versions of the steel-reinforced dendriform concrete columns that appear in the Great Workroom. The low carport ceiling creates a compression of space that is released when entering the main building, where the dendriform columns rise over two stories tall; the interior space thus appears larger than it is. Compression and release of space were concepts that Wright used in many of his designs, including the playroom in his Oak Park Home and Studio, the Unity Temple in Oak Park, Illinois, the Solomon R. Guggenheim Museum in New York City, and many others. Throughout the Great Workroom, which has no internal walls, the thin, white dendriform columns rise to circular "lily pad" tops that form the ceiling, with the spaces between the circles consisting of
