Henry Petroski's lyrical history of bridge builders in America is organized around five engineers: James Eads (inventor of the diving bell, which bridged Mississippi at St. Louis); Theodore Cooper (railroad bridge engineer and designer of the ill-fated Quebec Bridge); Gustav Lindenthal (Hell Gate Bridge, New York); Othmar Ammann (George Washington and Verrazano-Narrow bridges); and David Steinman (Mackinac bridge). Petroski's opening and closing chapters, "Imagine" and "Realize," remind us how a bridge starts out as a dream of engineering, but ends as a reality of compromise and maintenance. Edward Tenner says that "The profound contribution of Engineers of Dreams is to remind us that communication across generations may be the most important bridge of all."
