Thomas Graeme Nelson Haldane
Lieutenant-Commander Thomas Graeme Nelson Haldane, M.A., Sc.D, F.I.E.E., F.I.C.E., F.A.I.E.E., M.Cons.E. Royal Navy, Retired (14 December, 1897 – 24 June, 1981) was an officer of the Royal Navy during the First World War and saw action at the Battle of Jutland in H.M.S. Valiant, before retiring from the Naval Service to study Physics at Trinity College, Cambridge.
In his autobiographical writings, entitled Some Recollections and Reflections (p. 14), he writes: "…I met Admiral Jellicoe and his family on a more social occasion at Invergordon. Jellicoe was, I thought, much more of a thinker than Beatty, very approachable and blessed with a charming family. So, though my knowledge was obviously inadequate, I tended to support Jellicoe in all the controversy there was about Jutland and the merits of these two famous Admirals."
Haldane "devised a new type of electrical rangefinder on the Wheatstone Bridge principle, using the whole length of the ship as the base."
