William Callow (1812-1908) was one of the most accomplished and long-lived British watercolourists of the nineteenth century, whose career, spanning nearly eight decades of active work, carried the tradition of Richard Parkes Bonington's fluent, atmospheric watercolour technique deep into the twentieth century's threshold. Born in Greenwich, the son of a builder, he was apprenticed as a young boy to the engraver Theodore Henry Adolphus Fielding, and came under the wing of Fielding's brother, the landscape painter Anthony Vandyke Copley Fielding, himself later President of what became the Royal Watercolour Society and also represented in John Mitchell Fine Paintings' collection. In 1829 Callow travelled to Paris, where he began working alongside, and eventually took over the studio of, the watercolourist Thomas Shotter Boys, another painter held by the gallery, exhibiting regularly at the Paris Salon and quickly establishing a considerable reputation.
Callow's success in Paris culminated in his appointment, following the exhibition of a watercolour of Richmond Hill at the 1831 Salon, as drawing master to the family of King Louis-Philippe I, giving lessons to the Duc de Nemours and Princess Clémentine over several years. In 1838, while still resident in Paris, he was elected an Associate of the Society of Painters in Water Colours, an unusual honour for an artist not based in England that required special exemption from the Society's own rules; he became a full member in 1848 and went on to serve as its secretary from 1866 to 1870 and a trustee for fifteen years. He returned permanently to London in 1841 and continued travelling extensively across Britain and Europe, making his last foreign trip to Italy in 1892 at the age of eighty. Over his long career, Callow contributed more than fourteen hundred drawings to the Society's exhibitions, and by the time of his sole solo exhibition, held at the Leicester Galleries in 1907 shortly before his death, he was recognised as the oldest living British artist and, in the words of the Burlington Magazine, one of the last faithful exponents of the great tradition of British watercolour painting.
The watercolour by Callow held by John Mitchell Fine Paintings, a precisely dated Scottish view from 1849, exemplifies the fluent, on-the-spot topographical draughtsmanship that sustained his reputation across an unusually long career, and connects naturally within the gallery's collection to both Copley Fielding, his early teacher, and Thomas Shotter Boys, his close Parisian collaborator.
