Abstract

The article focuses on the history and development of the Union Stock Yard in Chicago, which opened on Christmas Day 1865 as a major livestock market and meatpacking center. Designed by Octave Chanute, the stockyard rapidly expanded to become the largest in the world, catalyzing the growth of Chicago’s meatpacking industry, notably through companies like Armour & Company and key figures such as Philip Danforth Armour and Gustavus Swift. The industry introduced innovative assembly-line slaughter methods that increased productivity but also led to environmental pollution and challenging labor conditions, sparking multiple strikes. The stockyard and meatpacking industry declined by the mid-20th century, closing in 1971, and the site has since been redeveloped into a successful industrial park employing thousands in newer industries.
