John Jellicoe (1859–1935) was a Royal Navy officer who fought in the Anglo-Egyptian War and Boxer Rebellion and commanded the Grand Fleet at the Battle of Jutland during the First World War. His handling of the fleet at that battle was controversial: he made no serious mistakes and the German High Seas Fleet retreated to port – at a time when defeat would have been catastrophic for Britain – but the British public was disappointed that the Royal Navy had not won a victory on the scale of the Battle of Trafalgar. Jellicoe later served as First Sea Lord, overseeing the expansion of the Naval Staff at the Admiralty and the introduction of convoys, but was removed at the end of 1917. He also served as the Governor-General of New Zealand in the early 1920s.Photograph: Bain News Service; restored by Adam Cuerden
