Quick Facts: SC Johnson Administration Building

  • Commissioned by: H.F. Johnson, Jr. 

  • Designed by: Frank Lloyd Wright.

  • Opened: 1939.

  • Celebrated as one of the top 25 buildings of the 20th century.

  • Houses the Great Workroom, which has more than one-half acre of workspace and is renowned for its soaring columns.

  • Wright called the columns “dendriform,” meaning tree-shaped. Because of their unique design, they are also called mushrooms, golf tees or lily pads.

  • The columns are just 9 inches in diameter at their base, but blossom to 18.5 feet in diameter at the top.

  • Nearly 200 special shapes of red-brown brick were created to create the curves of the building; the trim is Kasota Stone.

  • The glass tubing “windows” of the building were designed by Wright to refract light and cut glare. Laid end-to-end, there are about 43 miles of glass Pyrex® tubes.

  • Wright also designed more than 40 pieces of custom furniture for SC Johnson.

Quick Facts: SC Johnson Research Tower

  • Commissioned by: H.F. Johnson, Jr. 

  • Designed by: Frank Lloyd Wright.

  • Opened: 1950.

  • One of the tallest structures ever built on the cantilever principle.

  • Stands 153 feet tall. Its central core, which is 13 feet in diameter, extends 54 feet into the ground.

  • The tower is 40 feet square.

  • All 15 floors of the tower are supported by the “taproot” core, much like a tree supports its branches.

  • Of the 15 floors, six are square, with circular mezzanine floors above them, and there is one additional square floor on the second level.

  • More than 5,000 Pyrex® glass tubes serve as its windows.

  • The Raid®, Glade®, OFF!® and Pledge® brands were all invented in the tower.

  • SC Johnson stopped using the tower as a research lab in 1982, when new building codes required the addition of an external fire escape if it was going to remain in use. 

Quick Facts: Fortaleza Hall

  • Commissioned by: Fisk Johnson Designed by: Norman Foster and his firm, Foster + Partners

  • Opened: 2010.

  • Includes Legacy Gallery, which shares the history of the company, and The Commons, a gathering place for employees, including a dining area, fitness center, full service bank, concierge service and company store.

  • Home to the replica, twin-engine S-38 amphibious plane Sam Johnson flew to Brazil in 1998.

  • Home to The SC Johnson Gallery: At Home with Frank Lloyd Wright, which showcases a rotating selection of Wright’s designs and artifacts.

  • An 8,000-square-foot mural of white concrete features rasterized images of the Brazilian palm forest, recreated from a photo taken during H.F. Johnson, Jr.’s 1935 expedition.

  • The polyconic mosaic map on the floor traces Sam’s expedition and was created using 19,200 pieces of four different kinds of sustainably harvested wood.

  • Two grand staircases on the north and south sides of the building are dedicated to H.F. Johnson, Jr. and Sam Johnson, and feature quotes from them.

  • Three curved, sustainably harvested U.S. black walnut benches depict the expedition stops of both H.F. Johnson, Jr. and Sam Johnson. 

  • The vertical garden was designed by Patrick Blanc and holds nearly 2,500 plants and 79 species largely native to Central and South America.

  • The soundscape provides a 3-D veil of sound. It is computer-generated and linked to the U.S. National Oceanic Atmospheric Administration (NOAA) to compliment the weather and the time of day in Racine with sounds of Brazil. No two days sound alike.
