1885 First Skyscraper

Chicago from Lake Michigan

The Home Insurance Building, erected at the northeast corner of LaSalle and Adams streets (on the site now occupied by the west portion of the Field building), is called the first skyscraper.

Nine stories and one basement were completed in 1885. Two stories were added in 1891. The architect, Major William Le Baron Jenney, created the first load-carrying structural frame, the development of which led to the "Chicago skeleton" form of construction and the big skyscrapers of later years.

In this building, a steel frame supported the entire weight of the walls instead of the walls themselves carrying the weight of the building which was the usual method. After Jenney's accomplishment the sky was truly the limit so far as building was concerned. His first skyscraper revolutionized urban life because with higher buildings larger numbers of people could live and work in limited areas.

Note:

In my reading on skyscraper’s, that I did not take into account at the time is that it brought more people together in an isolated space, which would bring about the population explosion; since their would be more space then before for housing.
