Meatpacking turned Illinois’s livestock into one of America’s great industries, and turned its packing cities into gateways for immigrants seeking a first foothold. If your family worked the stockyards, their story runs through this trade.

From 1865 the Chicago Union Stock Yards were the greatest in the world — Armour and Swift built fortunes there, and Carl Sandburg called the city “Hog Butcher for the World.”
Immigrant and migrant labor
The killing floors and cutting rooms of Chicago’s Union Stock Yards were built on immigrant and migrant labor — the newest arrivals took the hardest, most dangerous jobs, and whole neighborhoods grew up around the plants. The packing house was often a family’s first foothold in America.
A record-rich industry
Packing towns generated dense records — city directories listing “packing house” and “butcher,” company employment files, union rolls, parish registers, and the death notices of a dangerous trade — all trails back to the worker who arrived.
