A historical look at styles of technological research and design. If it is true, as Tocqueville suggested, that social and class systems shape technology, research, and knowledge, then the effects should be visible both at the individual level and at the level of technical institutions and local environments. That is the central issue addressed in Constructing a Bridge, a tale of two cultures that investigates how national traditions shape technological communities and their institutions and become embedded in everyday engineering practice. Eda Kranakis first examines these issues in the work of two suspension bridge designers of the early nineteenth century: the American inventor James Finley and the French engineer Claude-Louis-Marie-Henri Navier. Finley--who was oriented toward the needs of rural, frontier communities--designed a bridge that could be easily reproduced and constructed by carpenters and blacksmiths. Navier--whose professional training and career reflected a tradition of monumental architecture and had linked him closely to the Parisian scientific community--designed an elegant, costly, and technically sophisticated structure to be built in an elite district of Paris. Charting the careers of these two technologists and tracing the stories of their bridges, Kranakis reveals how local environments can shape design goals, research practices, and design-to-construction processes. Kranakis then offers a broader look at the technological communities and institutions of nineteenth-century France and America and at their ties to technological practice. She shows how conditions that led to Finley's and Navier's distinct designs also fostered different systems of technical education as well as distinct ideologies and traditions of engineering research.The result of this two-tiered, comparative approach is a reorientation of a historiographic tradition initiated by Tocqueville (and explored more recently by Eugene Ferguson, John Kasson, and others) toward a finer-grained analysis of institutional and local environments as mediators between national traditions and individual styles of technological research and design.
Aims to modify the periodization for the American Enlightenment. Americans did accept an early and moderate Enlightenment characterised by the work of Locke and Newton. This collection highlights the functional nature of the Enlightenment in America.
This book deals with the period when iron became the dominant ’high-technology’ material, increasingly taking over from timber and masonry. It was necessary for the engines and machines of the new industries, but equally vital for the vast civil engineering works which supported this industrialisation. It was these works - mills, warehouses, dockyards, and above all bridges - which so impressed the public in the early 19th century. The papers selected here trace the evolving structural uses of cast and wrought iron in frames and roofs for buildings, and look in particular at the development of bridge design and construction, in America, France, and Russia, as well as in Britain. They cover the processes of design and testing, and at the same time throw much light on the attitudes and careers of the engineers themselves.
John Roebling was one of the nineteenth century's most brilliant engineers, ingenious inventors, successful manufacturers, and fascinating personalities. Raised in a German backwater amid the war-torn chaos of the Napoleonic Wars, he immigrated to the US in 1831, where he became wealthy and acclaimed, eventually receiving a carte-blanche contract to build one of the nineteenth century's most stupendous and daring works of engineering: a gigantic suspension bridge to span the East River between New York and Brooklyn. In between, he thought, wrote, and worked tirelessly. He dug canals and surveyed railroads; he planned communities and founded new industries. Horace Greeley called him "a model immigrant"; generations later, F. Scott Fitzgerald worked on a script for the movie version of his life. Like his finest creations, Roebling was held together by the delicate balance of countervailing forces. On the surface, his life was exemplary and his accomplishments legion. As an immigrant and employer, he was respected throughout the world. As an engineer, his works profoundly altered the physical landscape of America. He was a voracious reader, a fervent abolitionist, and an engaged social commentator. His understanding of the natural world, however, bordered on the occult and his opinions about medicine are best described as medieval. For a man of science and great self-certainty, he was also remarkably quick to seize on a whole host of fads and foolish trends. Yet Roebling held these strands together. Throughout his life, he believed in the moral application of science and technology, that bridges--along with other great works of connection, the Atlantic Cable, the Transcontinental Railroad--could help bring people together, erase divisions, and heal wounds. Like Walt Whitman, Roebling was deeply committed to the creation of a more perfect union, forged from the raw materials of the continent. John Roebling was a complex, deeply divided yet undoubtedly influential figure, and this biography illuminates not only his works but also the world of nineteenth-century America. Roebling's engineering feats are well known, but the man himself is not; for alongside the drama of large scale construction lies an equally rich drama of intellectual and social development and crisis, one that mirrored and reflected the great forces, trials, and failures of nineteenth century America.
