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 ...

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).

The Kelvin water dropper, invented by Scottish scientist William Thomson (Lord Kelvin) in 1867, [1] is a type of electrostatic generator. Kelvin referred to the device as his water-dropping condenser. The apparatus is variously called the Kelvin hydroelectric generator, the Kelvin electrostatic generator, or Lord Kelvin's thunderstorm.
Regarding the Relativity Principle, the moving magnet and conductor problem (possibly after reading a book of August Föppl) and the various negative aether drift experiments were important for him to accept that principle — but he denied any significant influence of the most important experiment: the Michelson–Morley experiment.

It had been long known that continuous electric currents flowed through the solid and liquid portions of the Earth, [5] and the collection of current from an electrically conductive medium in the absence of electrochemical changes (and in the absence of a thermoelectric junction) was established by Lord Kelvin. [6] [7] Lord Kelvin's "sea ...

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 ...
