George Johnstone Stoney FRS (15 February 1826 – 5 July 1911) was an Anglo-Irish physicist. He is most famous for introducing the term electron as the "fundamental unit quantity of electricity". He had introduced the concept, though not the word, as early as 1874 and 1881, and the word came in 1891. He published around 75 scientific papers during his lifetime.
Stoney was born at Oakley Park, near Birr, County Offaly, in the Irish Midlands, the son of George Stoney (1792–) and Anne Blood (1801–1883). The Stoney family is an old-established Anglo-Irish family. He attended Trinity College, Dublin, graduating with a B.A. degree in 1848. From 1848 to 1852 he worked as an astronomy assistant to William Parsons, 3rd Earl of Rosse at Birr Castle, County Offaly, where Parsons had built the world's largest telescope, the 72-inch Leviathan of Parsonstown. Simultaneously Stoney continued to study physics and mathematics and was awarded an M.A. by Trinity College Dublin in 1852.

Johnstone (Scots: Johnstoun,Scottish Gaelic: Baile Iain) is a town in the council area of Renfrewshire and larger historic county of the same name in the west central Lowlands of Scotland.
The town lies 3 miles (5 km) west of neighbouring Paisley and 12 miles (19 km) west of the centre of the city of Glasgow. Part of the biggest conurbation in Scotland, Johnstone is at the western edge of the Greater Glasgow Urban Area.
The town was a planned community created in the latter half of the 18th century by the local Laird, George Ludovic Houston who held an estate in the town, the remains of which are known as Johnstone Castle. Industrial development brought coal mining, thread-making and cotton weaving to Johnstone causing it to grow considerably in size, expanding out in the 1930s with a number of newly built residential areas which addressed the problem of population density in the historic area of the town. Today it supports a small commercial centre and serves as a commuter settlement for Paisley and Glasgow.
Johnstone is a surname. It is a variant of the similar surname Johnston which in most cases is a habitational surname derived from several places in Scotland.
