Thomas Campbell entered formal training at the Royal Academy Schools in 1818 as a mature student, under the patronage of Gilbert Innnes, Deputy Governor of the Bank of Scotland, who's support enabled him to establish a studio and reputation in Rome. Campell had attracted the attention of the Duke of Devonshire by 1824, who commissioned a statue of Princess Pauline Borghese. From 1827 to 1857 he exhibited at the Academy and continued to receive commissions from many Scottish clients, including the Duke of Buccleuch in 1847. Typically he modelled his subjects in classical style drapery, and was appreciated by his contemporaries for a purity of surface and the ability to convey the 'individual likeness' of the sitter.
