A warmly biassed biography of a man with a mission and one whose Naval career was strewn with flayed subordinates and superiors, this concentrates on the project of a ""true"" submarine which resulted in the nuclear powered Nautilus, to be launched 1 January, 1954. An Annapolis graduate, undiplomatic, urgent, a driving doer, Rickover got the chance for study at Oak Ridge and there, with his picked Naval Group, considered himself head man for the submarine program. Top brass opposition did not stop him, the Naval Group made fast progress, firmed up at Los Alamos, and his unorthodox methods of dealing with civilians and industrialists curled official hair. But interest was aroused, the Nautilus became a ft accomp and Rickover at last was promoted to Rear-Admiral. Technicalities head this to a science minded audience but do not hinder the portrayal of a forceful personality.
