American Bridge Patents

Emory L. Kemp, who writes and speaks actively on historic structures, is founder and first director of the Institute for the History of Technology and Industrial Archaeology at West Virginia University. Kemp edited American Bridge Patents with Shelly Birdsong-Maddex, who helped assemble patent records for this publication while pursuing her graduate studies. Eric N. DeLony has been at the forefront of efforts to document and preserve historic bridges under the auspices of the National Park Service. Larry N. Sypolt has been involved in numerous projects combining his expertise in archival work and historic preservation studies.

"Patents and their drawings provide a firsthand record of the development of technology. In American Bridge Patents, the reader encounters the pioneering work of some of the most creative and influential inventors of bridges that have become such a treasured part of our structural engineering history and heritage." Henry Petroski, Duke University "If you don't know your trusses; if you don't know a 'Fink' from a 'Linville', or the difference between a 'Pratt', a 'Howe', and a 'Whipple', then this is the book for you. It provides a glimpse into a treasury of American engineering history in the US National Archives, in the form of a collection of bridge patentees' original ink and watercolour bridge drawings."
