George Cattermole RWS (1800 –1868) was a British painter and illustrator, chiefly in watercolours. He was a friend of Charles Dickens and many other literary and artistic figures.
At the age of fourteen he began working as an architectural and topographical draughtsman for the antiquary John Britton. Afterwards he contributed designs to be engraved in the annuals then so popular, then progressed into watercolour painting, becoming an associate of the Royal Watercolour Society in 1822, and a full member in 1833. At the Paris Exhibition of 1855 he received one of the five first-class gold medals awarded to British painters.
