Lives of the Philadelphia Engineers examines the emergence of a new class of industrial entrepreneur and the world it confronted and shaped. Historians are reluctant to examine nineteenth-century American business leaders as a social group and this study helps remedy the defect. This book interweaves a history of the social and economic development of the largest centre of machine building in nineteenth-century America with the dramatic political narrative of sectional conflict, Civil War and Reconstruction. Crossing and re-crossing the boundary between industrial and political history, it throws new light on the process of industrialisation, the Civil War conflict, and the contested governance of nineteenth-century cities. While this study is firmly rooted in the experience of Philadelphia's machine builders, its historiographic significance extends to many of the important themes of mid-century American history. By rejecting the conventional viewpoint that timid manufacturers were conservative supporters of the plantation South and insisting that workshop owners rejected slavery, this study reinvigorates one of the Civil War's enduring interpretative battles. Of interest to scholars of business, economic, social, labour, education, urban and Civil War history, it will no doubt stimulate further debate and add a new angle to our understanding of nineteenth-century America.

The Sellers brothers, Samuel and George, came to North America in 1682 as part of the Quaker migration to William Penn’s new province on the shores of the Delaware River. Across more than two centuries, the Sellers family—especially Samuel’s descendants Nathan, Escol, Coleman, and William—rose to prominence as manufacturers, engineers, social reformers, and urban and suburban developers, transforming Philadelphia into a center of industry and culture. They led a host of civic institutions including the Franklin Institute, Abolition Society, and University of Pennsylvania. At the same time, their vast network of relatives and associates became a leading force in the rise of American industry in Ohio, Georgia, Tennessee, New York, and elsewhere.Engineering Philadelphia is a sweeping account of enterprise and ingenuity, economic development and urban planning, and the rise and fall of Philadelphia as an industrial metropolis. Domenic Vitiello tells the story of the influential Sellers family, placing their experiences in the broader context of industrialization and urbanization in the United States from the colonial era through World War II. The story of the Sellers family illustrates how family and business networks shaped the social, financial, and technological processes of industrial capitalism. As Vitiello documents, the Sellers family and their network profoundly influenced corporate and federal technology policy, manufacturing practice, infrastructure and building construction, and metropolitan development. Vitiello also links the family’s declining fortunes to the deindustrialization of Philadelphia—and the nation—over the course of the twentieth century.

“Another gem from one of the world’s justly celebrated historians specializing in unusual and always fascinating subjects and people.” — Booklist (starred review) The revered New York Times bestselling author traces the development of technology from the Industrial Age to the Digital Age to explore the single component crucial to advancement—precision—in a superb history that is both an homage and a warning for our future. The rise of manufacturing could not have happened without an attention to precision. At the dawn of the Industrial Revolution in eighteenth-century England, standards of measurement were established, giving way to the development of machine tools—machines that make machines. Eventually, the application of precision tools and methods resulted in the creation and mass production of items from guns and glass to mirrors, lenses, and cameras—and eventually gave way to further breakthroughs, including gene splicing, microchips, and the Hadron Collider. Simon Winchester takes us back to origins of the Industrial Age, to England where he introduces the scientific minds that helped usher in modern production: John Wilkinson, Henry Maudslay, Joseph Bramah, Jesse Ramsden, and Joseph Whitworth. It was Thomas Jefferson who later exported their discoveries to the fledgling United States, setting the nation on its course to become a manufacturing titan. Winchester moves forward through time, to today’s cutting-edge developments occurring around the world, from America to Western Europe to Asia. As he introduces the minds and methods that have changed the modern world, Winchester explores fundamental questions. Why is precision important? What are the different tools we use to measure it? Who has invented and perfected it? Has the pursuit of the ultra-precise in so many facets of human life blinded us to other things of equal value, such as an appreciation for the age-old traditions of craftsmanship, art, and high culture? Are we missing something that reflects the world as it is, rather than the world as we think we would wish it to be? And can the precise and the natural co-exist in society?
