John Mercer Brooke, who joined the United States Navy in 1841, was both a witness and key contributor to changes in the navies during the 19th century (ordnance was improved, steam superseded sail, etc.). He was a naval scientist and designer. He invented an effective deep-sea sounding lead which made possible the laying of the Atlantic cable. He led major explorations of the North Pacific Ocean and the coast of Japan. 372 p. Index.
