Campbell was born in 1764 at Tombea, Loch Lubnaig, and first educated at the grammar school, Callander, was the second son of a carpenter who, falling into straitened circumstances, removed to Edinburgh, where he died when Alexander was eleven years old.
The result was that 'our neighbour, Lady Cunningham, sent to beg the boys might not all be flogged precisely at the same hour, as, though she had no doubt the punishment was deserved, the noise of the concord was really dreadful' (Notes to Scott's Autobiography, in chap.

Scott thought the picture might be highly coloured, and at any rate Constable bestowed on him 'many substantial benefits,' as he gratefully acknowledges in a letter written the year before his death, which took place from an attack of apoplexy 15 May 1824.
Scott, who wrote an obituary notice of him in the 'Edinburgh Weekly Journal,' says that, though his acquirements were considerable, 'they did not reach that point of perfection which the public demand of those who expect to derive bread from the practice of the fine arts.'
