Home Insurance Building completed in Chicago, the first skyscraper

Background. Chicago, located on the western shore of Lake Michigan, made noted contributions to urban planning and architecture, including the Chicago School and the steel-framed skyscraper. During its rebuilding period, the city constructed the world's first skyscraper in 1885 using steel-skeleton construction. The Home Insurance Building rose that year as Chicago ushered in the skyscraper era, which would be followed by many other cities around the world.

Design and Construction. Designed by William Le Baron Jenney in 1884, the Home Insurance Building was completed the following year. It was the first tall building supported by a fireproof structural steel frame, though it also incorporated reinforced concrete. Jenney's use of metal columns and beams instead of traditional stone and brick allowed for the support of upper levels. The building's unique architecture and weight-bearing frame are central to its historical significance.

Historical Reception. The Home Insurance Building is often cited as the world's first skyscraper due to its design and height. However, contemporary Chicago press did not refer to it as such at the time of construction. An 1884 list of skyscrapers included buildings taller than the Home Insurance Building, which was completed in 1885. Its status as the first skyscraper was formally accorded by the time of its centennial in 1985.
