Philadelphia’s manufacturing history is the subject of a new book by archivist and historian Jack McCarthy, best known to readers of The Encyclopedia of Greater Philadelphia as the author of many of our music topics. In the Cradle of Industry & Liberty: A History of Manufacturing in Philadelphia, published for the Manufacturing Alliance of Philadelphia by HPN Books, traces local manufacturing from the colonial period to the transition to machine-based factory production methods, the development of manufacturing on a massive scale, and the dramatic downsizing in manufacturing that led to the city’s transition to a post-industrial, service-based economy. This month, McCarthy will talk about the topics of his book at a meeting of the Philadelphia Association of Tour Guides on January 11 and at the annual dinner of the Philadelphia Chapter of the Society for Industrial Archaeology on January 20.
