A comprehensive history of the first three decades of underwater exploration in antebellum America. Winner of the 2016 Dr. Art Bachrach Literary Award presented by the Historical Diving Society Silver Medalist, 2017 Independent Publisher Book Awards in the Sports/Fitness/Recreation Category Beginning in 1837, some of the most brilliant engineers of America's Industrial Revolution turned their attention to undersea technology. Inventors developed practical hard-helmet diving suits, as well as new designs of submarines, diving bells, floating cranes, and undersea explosives. These innovations were used to clear shipping lanes, harvest pearls, mine gold, and wage war. All of these underwater technologies were brought together by entrepreneurs, treasure-hunters, and daring divers in the 1850s to salvage three infamous shipwrecks on Lake Erie, each of which had involved the loss of hundreds of lives, as well as the worldly goods of the passengers. The prospect of treasure, combined with the national notoriety of these disasters, soon attracted the attention of local adventurers and the country's leading divers and marine engineers. In The Heroic Age of Diving , Jerry Kuntz shares the fascinating stories of the pioneers of underwater invention and the brave divers who employed the new technologies as they raced with-and against-marine engineers to salvage the tragic wrecks of Lake Erie.
