The Royal Watercolour Society (originally called the Society of Painters in Water Colours, briefly the Society of Painters in Oil and Watercolours, and for much of its existence the Royal Society of Painters in Water Colours) is an English institution of painters working in watercolours. The Royal Watercolour Society is a centre of excellence for water-based media on paper, which allows for a diverse and interesting range of approaches to the medium of watercolour. The Society's offices are at Bankside Gallery in London.
Its members, or associates, use the postnominal initials RWS. They are elected by the membership, with typically half a dozen new associates joining the Society each year. The current president is Jill Leman, who was elected in April 2017.
The society was founded as the Society of Painters in Water Colours in 1804 by William Frederick Wells. Its original membership was William Sawrey Gilpin, Robert Hills, John Claude Nattes, John Varley, Cornelius Varley, Francis Nicholson, Samuel Shelley, William Henry Pyne and Nicholas Pocock. The members seceded from the Royal Academy where they felt that their work commanded insufficient respect and attention.
In 1812, the Society reformed as the Society of Painters in Oil and Watercolours, reverting to its original name in 1820.
In 1831 a schism created another group, the New Society for Painters in Water Colours, and so the 1804 group became known as the Old Water Colour Society, and just the Old Society. The New Society subsequently became the Royal Institute of Painters in Water Colours, which still exists today.
The Old Society obtained its Royal charter 1881 under the presidency of Sir John Gilbert as the Royal Society of Painters in Water Colours. In 1988, it changed its name again to the Royal Watercolour Society, by which it had always previously been generally known.
