Admiral Sir Henry Jackson, the often-forgotten First Sea Lord between Fisher and Jellicoe, had an important earlier technical career. Jackson achieved continuous ship-to-ship wireless communication over roughly three miles in 1896, when the feat was still extraordinary. After taking command of the Eclipse-class protected cruiser HMS Juno in 1899, he ensured that the ship carried wireless equipment and continued experimenting with it. He later worked with Marconi as naval radio moved from demonstration to routine fleet use. Juno's conventional cruiser form makes the invisible communications innovation easy to overlook. An officer's repeated practical adoption can turn an experimental technology into an institutional naval capability.
