Engineers of Dreams : Great Bridge Builders and the Spanning of America

Petroski reveals the science and engineering--not to mention the politics, egotism, and sheer magic--behind America's great bridges, particularly those constructed during the great bridge-building era starting in the 1870s and continuing through the 1930s. It is the story of the men and women who built the St. Louis, the George Washington, and the Golden Gate bridges, drawing not only on their mastery of numbers but on their gifts for persuasion and self-promotion. It is an account of triumphs and ignominious disasters (including the Tacoma Narrows Bridge, which literally twisted itself apart in a high wind). And throughout this grandly engaging book, Petroski lets us see how bridges became the "symbols and souls" of our civilization, as well as testaments to their builders' vision, ingenuity, and perseverance. "Seamlessly linked...With astonishing scope and generosity of view, Mr. Petroski places the tradition of American bridge-building in perspective."--New York Times Book Review Petroski has already initiated readers into the hidden mysteries of such everyday artifacts as the lead pencil, the paper clip, the zipper, and Post-it notes. Now, he makes a considerable jump in scale in order to contemplate those "dry paths" across the rivers and inlets of our cities and countrysides--those eminently practical yet strikingly beautiful edifices that persist in taking our collective breath away--bridges. 131 illustrations. In his previous books, Henry Petroski has initiated us into the hidden mysteries of such everyday artifacts as the lead pencil, the paper clip, the zipper, and the Post-it note. Now, with Engineers of Dreams, he makes a jump in scale to contemplate those "dry paths" across the rivers and inlets of our cities, those "hard crossings" over the gulches and ravines of our countrysides, those eminently practical but inescapably aesthetic edifices that persist in taking our breath away (when we're not taking them for granted): bridges. The great era of American bridge building - which from the 1870s through the 1930s gave us such landmarks as the Eads Bridge across the Mississippi, the Hell Gate Bridge across the East River, the George Washington Bridge across the Hudson, and the Golden Gate Bridge at the mouth of San Francisco Bay - called for a special breed of engineer: equal parts dreamer, inventor, and entrepreneur. Since the building of any bridge is necessarily a collaborative effort, engineers of dissimilar philosophies and all-too-similar egos were thrown together on project after project, making for an ongoing, interwoven human and technological drama. This book reveals the story behind the era of American bridge building, from the 1870s to the 1930s, looking at the engineers who designed them and the professional, economic, political, and personal conflicts that occurred in the course of the bridges being built
