This book offers a historical view of diving, including contributions by Jacques-Yves Cousteau and edited by James Dugan, Cousteau's literary associate. Written in 1965, it features pictures of the SCUBA equipment of the time, as well as the pioneers of SCUBA and their exploits, including the raising of the Union ironclad gunboat "Cairo," an account of an attempt to blow up the harbor of Malta during WWII, a trip to the North Pole aboard the submarine "Sargo," and the story of an Israeli underwater archaeologist searching for shipwrecks from biblical times.
