Considered the first American skyscraper, the 10-story Home Insurance Building in Chicago was the first tall building to be supported by a metal skeleton of vertical columns and horizontal beams. Engineer William LeBaron Jenney discovered that thin pieces of steel could support a tall building as well as thick stone walls could. The steel necessary to carry Jenney's 10-story building weighed only one-third as much as a 10-story building made of heavy masonry. Since the steel skeleton supported the weight of the entire building and the exterior wall was really just a skin to keep out the weather, the Home Insurance Building was the first tall building to have many windows. Jenney’s steel frame brought floor space and windows to the structure we now know as the modern skyscraper.
Here's how this skyscraper stacks up against the biggest skyscrapers in the world.
