Founded on a triangle of land bounded by two mighty rivers, Pittsburgh has a long and storied chapter in American history. Currently the second-largest city in the Commonwealth of Pennsylvania, Pittsburgh grew from a fur-trading post into Steeltown, U.S.A. Its immense steel factories symbolized America's new forefront in the Industrial Age, even as the smoke and soot from those factories left the city polluted and filthy. After decades of change, Pittsburgh today is considered one of the most livable cities in America. Historic Photos of Pittsburgh examines the growth and change of this important American city. Nearly 200 photographs spanning two centuries have been collected and captioned with compelling text. Rich in historic detail, filled with images of the past, this book captures the power and might of a great industrial city and is a must-have for both historians and the general reader.
