| Title | Jackson, Sir Henry Bradwardine: certificate of election to the Royal Society |
| Citation | Naval Attache to the British Embassy, Paris. Invented (1886) a practical system of electrically illuminating gun sights for firing at night, which was adopted and used for some years in HM Navy, but has since been replaced by later methods. Proved (1888) that considerable stability is necessary in order that a totally submerged automobile torpedo may maintain a straight course. Has given much attention to the theory and practice of aerial telegraphy. Invented a serviceable apparatus for signalling between ships at sea without wires. Proved that if the Hertzian oscillations are transmitted and received by vertical wires, the distance to which effective signals can be sent tends to vary within limits as the product of the lengths of the wires. |
