There was probably no more controversial figure in British naval history than 'Jacky' Fisher, the architect of Jellicoe's fleet in the Great War. On a basis of extended research and much new material, this biography examines hitherto unanswered question relating to 'the Fisher era'. Special attention is paid to the earlier part of a career extending from the age of sail to the development of sonar in the Great War. Personalities loom large, from hard-bitten sailors of the Crimean War to Lord Charles Beresford and Winston Churchill&mdsh;to say nothing of the 'demonic' Fisher, with his passions and organizational genius.
