James Thomson Bottomley

James Thomson Bottomley FRS FRSE (10 January 1845 – 18 May 1926) was an Irish-born British physicist.

He was born in Fort Breda, County Down in Ireland, on 10 January 1845, the son of William Bottomley JP, a merchant in nearby Belfast.

In 1872 his uncle Lord Kelvin proposed him as a Fellow of the Royal Society of Edinburgh, and this was duly accepted.

Bottomley engaged Dr John Macintyre an electrical expert at Glasgow Royal Infirmary to make the demonstration.

[4] In 1899, again with his uncle, the Glasgow engineering firm of Kelvin, Bottomley & Baird (K.B.B) was formed, specialising in gauges and meters but also producing loudspeakers and telephones.
