Video description from @notgpodcast
Chicago, 1885: the 10-storey Home Insurance Building is completed, 138 feet (about 42 m) tall. An iron frame carried much of its load, so the walls could be thinner and the windows bigger. It stood until 1931.
Historians still debate the title, so it is often called the world's first skyscraper.
