This rosette was designed by architect William Le Barron Jenney for the Home Insurance Building, completed in 1885 and was located at northeast corner of LaSalle and Adams. It is recognized as the first skyscraper. When the building was demolished in 1931, Chicagoan Charles Rubens saved this rosette, later donating it to the Chicago Historical Society.
The Home Insurance Building, completed in 1885 by architect William Le Barron Jenney, illustrates the innovation and engineering expertise of the First Chicago School. Jenney trained as an architect in Paris and served as an engineer during the Civil War; a diverse education that produced the idea of supporting a building through interior steel framing instead of heavy external walls. This innovation, known as steel skeleton construction, allowed buildings to be taller, built faster, and made them more fireproof- laying the groundwork for skyscraper construction. Jenney's choice of steel framing is a testament to Chicago's booming steel industry; which only grew as steel framing became the standard. Jenney's office became the training ground for the "First Chicago School" a group of nineteenth-century Chicago architects known for their forward-thinking style.
