Emory Kemp is the founder and director of the Institute for the History of Technology and Industrial Archaeology at West Virginia University, where he also served as a chair and professor of civil engineering and a professor of history. This collection of essays encompasses over fifty years of his research in the field of the history of technology.

Within these twelve essays, Kemp describes and analyzes nineteenth century improvements in building materials such as iron, steel, and cement; roads and bridges, especially the evolution of the suspension bridge; canals and navigable rivers, including the Ohio River and its tributaries; and water supply systems. As one of the few practicing American engineers who also researches and writes as an academic, Kemp adds an important historical context to his work by focusing not only on the construction of a structure but also on the analytical science that heralds a structure’s design and development.

Over the Alleghenies: Early Canals and Railroads of Pennsylvania is the definitive history of the state of Pennsylvania’s incredible canal and railroad system. Although often condemned as a colossal failure, this construction effort remains an innovative, magnificent feat that ushered in modern transportation to Pennsylvania and the entire country. With extensive primary research, over one hundred illustrations, newspapers clippings, and charts and graphs, Over the Alleghenies examines and dissects the infrastructure project that bankrupted the wealthiest state in the Union.
