Although multi-storey (including narrow) buildings and even entire cities of them (for example, Shibam in Yemen, San Gimignano in Italy) were also built in the previous history of mankind, the building of the Insurance Company built in 1885 in Chicago is considered to be the first skyscraper (Home Insurance Building), which existed until 1931. Originally it had only 10 floors and a height of 42 m; later, in 1891, two more floors were built on, and the height of the building grew to 54.9 m. The author of the project, American architect William Le Baron Jenny, proposed an innovative construction technology, in which the supporting framework was used for the first time. Traditionally, the role of the supporting structure was performed by external walls. Based on the fact that the specific strength of steel is about 50 times higher than that of the highest-quality concrete and masonry or brick masonry, buildings began to rest on a steel frame supporting both external and internal walls. Thanks to the supporting frame, the total weight of the structures was reduced by almost a third. The architect did not dare to completely abandon other supporting structures, therefore the building also had a load-bearing rear wall and granite columns.
