History[change | change source]
Originally, the word skyscraper meant a tall sail on a sailing ship. Over time, the word's meaning has changed, and today it means a tall building. Until the nineteenth century, buildings taller than six stories tall were not common. Tall buildings made of weak materials would fall down. In addition, people did not like walking up many steps and running water could only be brought up to fifty feet (15m) high.
Better technology helped make skyscrapers more common. Stronger building materials such as steel and reinforced concrete were developed, so stronger buildings could be made. Water pumps brought water up to heights above fifty feet.
The first skyscraper, The Home Insurance Building, was built in Chicago, Illinois, USA. William LeBaron Jenney designed it. The building, ten stories high, was built in 1884 and 1885. It was destroyed in 1931 because they wanted to build another building in its previous place.
