Sir Henry Jackson Admiral of the Fleet Sir Henry Jackson,

who has died at the age of seventy-four, held some of the highest com- mands, both on land and afloat, without being much known to the public. His silent industry and high technical competence earned for him the complete confidence of the Navy. It was as a leader of research that he did his most fruitful work and was made a Fellow of the Royal Society. He had been experimenting in an embryonic wireless telegraphy for some time before he met Signor Marconi, and they then carried out many experiments together. When he first called the attention of the Admiralty to the importance of wireless telegraphy the Admiralty rejected his proposals on the ground that an installation on board ship would probably explode the magazines He succeeded Lord Fisher as First Sea Lord in the second year of the War. He had already been advising Mr. Churchill on the Dardanelles, and it is due to him to say how strongly he deprecated a naval attack without military support. When Mr. Lloyd George succeeded Mr. Asquith as Prime Minister Sir Henry retired from his post of First Sea Lord. His co-operation with the Navy had been extremely harmonious. He and Lord Jellicoe were united in a single policy.
