In 1906 U.S. Steel laid out an entire city on the Lake Michigan dunes and named it Gary for its chairman. The mills of Gary, East Chicago, and Hammond drew Southern and Eastern European immigrants — and later Southern Black migrants and Mexican workers — into one of the great steel districts on earth.
The limestone belt
Around Bedford and Bloomington, the Salem limestone quarries produced the pale, durable stone that faced the Empire State Building, the Pentagon, and countless courthouses and cathedrals. Generations of quarrymen and stone carvers built a craft culture in the hills.
The people of industrial Indiana
The mills and quarries pulled whole communities into company towns and mill neighborhoods, their records — census occupations, union rolls, parish registers — the trail back to the immigrant worker who arrived.
