He was born '
John Mitchell on Shore Street in
Campbeltown in western Scotland on 1 December 1861 to John Mitchell (d.1896), a local grocer, and his wife, Janet McMillan (1836–1920). He adopted the name Campbell in later life, probably in reference to his place of birth. His maternal grandfather, Malcolm McMillan, owned the "Steamboat Inn" in Campbeltown. He attended Campbeltown Grammar School until around 1872. He was apprenticed as a lawyer to the local (and still extant) firm of C & D MacTaggart. However, the local artist
William McTaggart actively encouraged him to pursue art, and in the summer of 1874 he joined
The Trustees Academy in Edinburgh to retrain as an artist. He began exhibiting at the
Royal Scottish Academy in 1886. In 1887 he went to
Paris to study under
Jean-Joseph Benjamin-Constant, returning to Edinburgh in 1890. He presumably lived with his father, who had retired to Edinburgh in 1889 and was living at 151 Bruntsfield Place, then a very new and exclusive flat, and exceptionally larger than the average property. In 1901 he spent several months in Galloway in south-west Scotland studying the ever-changing skies. In 1903 he settled in
Corstorphine in west
Edinburgh, remaining there for the rest of his life. He was elected ARSA in 1904 and full RSA in 1919. He died at home, Duncree on Clermiston Road on
Corstorphine Hill in western Edinburgh on 15 February 1922. John Campbell Mitchell is buried in the churchyard of Gogar Parish Church, Edinburgh ==Known works==
