Lord Kelvin was commemorated on the £20 note issued by the Clydesdale Bank in 1971; in the current issue of banknotes, his image appears on the bank's £100 note. He is shown holding his adjustable compass and in the background is a map of the transatlantic cable.
The first tide predicting machine (TPM) was built in 1872 by the Légé Engineering Company. [11] A model of it was exhibited at the British Association meeting in 1873 [12] (for computing 8 tidal components), followed in 1875-76 by a machine on a slightly larger scale (for computing 10 tidal components), was designed by Sir William Thomson (who later became Lord Kelvin).

In 1899, Ayrton supported Hertha on her way to being elected the first woman member of the Institution of Electrical Engineers and the Royal Society awarded her a Hughes Medal in 1906. Their daughter Barbara Ayrton-Gould became a Labour MP; grandson Michael Ayrton was an artist and sculptor.
He was born in Edinburgh on 24 October 1868, the eldest son of Alexander Erskine Erskine-Murray , Sheriff of Glasgow (1832-1907), and his wife, Helen Pringle, [1] daughter of Robert Pringle of Symington. [2] In 1886 he began study under Lord Kelvin at Glasgow University assisting Kelvin in electrical experiments from 1888 and graduating BSc in ...
One of the earliest practical uses of Thomson's concepts was a tide-predicting machine built by Kelvin starting in 1872–3. On Lord Kelvin's advice, Thomson's integrating machine was later incorporated into a fire-control system for naval gunnery being developed by Arthur Pollen, resulting in an electrically driven, mechanical analogue ...
Perry worked as Lord Kelvin's assistant at the University of Glasgow, and later became professor of mechanical engineering at Finsbury Technical College. [1] He was a colleague of William Edward Ayrton and John Milne at the Imperial College of Engineering in Tokyo, 1875–79, and was also a Fellow of the Royal Society. He was professor of ...
Following standard procedure for the time, the paper was first read to the Royal Society on 8 December 1864, having been sent by Maxwell to the society on 27 October. It then underwent peer review, being sent to William Thomson (later Lord Kelvin) on 24 December 1864. [4]
An entirely new system, providing continuous automatic recording, was installed by Lord Kelvin personally in the early 1860s. This device, based on Kelvin's water dropper potential equaliser with photographic recording, [17] was known as the Kew electrograph. It provided the backbone of a long and almost continuous series of potential gradient ...
