At the age of fifteen he was apprenticed to the goldsmith James Gilliland of Edinburgh, and various pieces of jewellery, mourning rings and the like, adorned with minute drawings on ivory by his hand, still exist.
Gilliland watched the progress of his pupil with interest, and introduced him to David Martin, who had been the favourite assistant of Allan Ramsay the Latter, and was now the leading portrait painter in Edinburgh.
In London he was kindly received by Sir Joshua Reynolds, the president of the Royal Academy, who advised him on what to study in Rome, especially recommending the works of Michelangelo, and gave Raeburn letters of introduction for Italy.
In Rome he met his fellow Scot Gavin Hamilton, Pompeo Girolamo Batoni and Byers, an antique dealer whose advice proved particularly useful, especially the recommendation that "he should never copy an object from memory, but, from the principal figure to the minutest accessory, have it placed before him."
Sir Walter Scott, Hugh Blair, Henry Mackenzie, Lord Woodhouselee, William Robertson, John Home, Robert Fergusson, and Dugald Stewart were resident in Edinburgh, and were all painted by Raeburn.
Apart from himself, Raeburn painted only two artists, one of whom was Sir Francis Leggatt Chantrey, the most important and famous British sculptor of the first half of the 19th century.
"[citation needed] In 1812 he was elected president of the Society of Artists in Edinburgh; and in 1814 associate, and in the following year full member, of the Royal Scottish Academy.
He was able to produce a telling and forcible likeness; his work is distinguished by powerful characterisation, stark realism, dramatic and unusual lighting effects, and swift and broad handling of the most resolute sort.
David Wilkie recorded that, while travelling in Spain and studying the works of Diego Velázquez, the brushwork reminded him constantly of the "square touch" of Raeburn.
[3] This attitude partly explains the often coarse modelling and clashing colour combinations he employed, in contrast to the more refined style of Thomas Gainsborough and Reynolds.
He is buried in St. Cuthbert's churchyard against the east wall (the monument erected by Raeburn in advance) but also has a secondary memorial in the Church of St John the Evangelist, Edinburgh.
