The Cumberland Market Group was a short-lived artistic grouping in early twentieth century London. The group met in the studio of Robert Bevan in Cumberland Market,  the old hay and straw market off Albany Street, and held one exhibition. 
London is the capital and largest city of both England and the United Kingdom. Standing on the River Thames in the south-east of England, at the head of its 50-mile (80 km) estuary leading to the North Sea, London has been a major settlement for two millennia. Londinium was founded by the Romans. The City of London, London's ancient core − an area of just 1.12 square miles (2.9 km2) and colloquially known as the Square Mile − retains boundaries that follow closely its medieval limits. The City of Westminster is also an Inner London borough holding city status. Greater London is governed by the Mayor of London and the London Assembly.
Robert Polhill Bevan was a British painter, draughtsman and lithographer. He was a founding member of the Camden Town Group, the London Group, and the Cumberland Market Group.
Cumberland Market was a London market between Regent's Park and Euston railway station. It was built in the early 19th century and was London's hay and straw market for a hundred years until the late 1920s. An arm of the Regent's Canal was built to the market. The market was surrounded by modest housing, and in the early 20th century became an artistic community. The original houses were demolished during and after the Second World War and it is now a housing estate, known as Regent's Park Estate.
Robert Bevan took the rooms on the first floor of 49 Cumberland Market, north of Regent's Park, in April 1914, after the break-up of the Camden Town Group and the formation of its successor, the London Group. He had been a founder member of both organizations.  He held meetings there with his friends, and these became a formalised group towards the end of the year, founded by him with fellow Camden Town Group members, Charles Ginner and Harold Gilman, who began to work with the style called Neo-Realism . 
Regent's Park is one of the Royal Parks of London. It lies within north-west London, partly in the City of Westminster and partly in the London Borough of Camden. It contains Regent's University London and the London Zoo.
The Camden Town Group was a group of English Post-Impressionist artists active 1911–1913. They gathered frequently at the studio of painter Walter Sickert in the Camden Town area of London.
Charles Isaac Ginner (1878–1952) was a British painter of landscape and urban subjects. Born in the south of France at Cannes, of British parents, in 1910 he settled in London, where he was an associate of Spencer Gore and Harold Gilman and a key member of the Camden Town Group.
They defined what they did as exploring the shapes and colours of daily life (in particular those of north-west London), while also paying attention to their proper disposition compositionally and maintaining sensitivity to the medium of paint itself as key to an expressive image; the strong emphasis on natural observation was a differentiation from the Camden Town Group.   These principles were announced in a manifesto by Ginner published in New Age on 1 January 1914, and also employed as the preface to a joint show that year by Gilman and Ginner. It spoke against the "decorative" features of Post-Impressionist followers, as well as attacking academic art. 
Post-Impressionism is a predominantly French art movement that developed roughly between 1886 and 1905, from the last Impressionist exhibition to the birth of Fauvism. Post-Impressionism emerged as a reaction against Impressionists' concern for the naturalistic depiction of light and colour. Due to its broad emphasis on abstract qualities or symbolic content, Post-Impressionism encompasses Les Nabis Neo-Impressionism, Symbolism, Cloisonnism, Pont-Aven School, and Synthetism, along with some later Impressionists' work. The movement was led by Paul Cézanne, Paul Gauguin, Vincent van Gogh, and Georges Seurat.
In 1915 they were joined by John Nash.  In April of that year the only exhibition of the Cumberland Market Group was held in the Goupil Gallery. The group was subsequently enlarged by the addition of the American artist Edward McKnight Kauffer  and by Christopher Nevinson, but it held no further formal exhibitions. From 1916 to 1917 a School of Painting was run in Soho, based on the group's artistic philosophy.  Goupil’s continued to be of help by allowing the group's Saturday afternoon "At Homes" to be moved to their Grey Room.  Although not officially dissolved, the group lapsed after Gilman's death in 1919. 
John Northcote Nash was a British painter of landscapes and still-lives, and a wood engraver and illustrator, particularly of botanic works. He was the younger brother of the artist Paul Nash.
Goupil & Cie was a leading art dealership in 19th-century France, with headquarters in Paris. Step by step, Goupil established a worldwide trade in fine art reproductions of paintings and sculptures, with a network of branches and agents in London, Brussels, The Hague, Berlin and Vienna, as well as in New York City and Australia. Instrumental for this expansion were the Ateliers Photographiques, a plant north of Paris, in Asnières, which took up work in 1869. The leading figure was Adolphe Goupil (1806–1893). His daughter Marie married the French artist Jean-Léon Gérôme.
Edward McKnight Kauffer was an American artist and graphic designer who lived for much of his life in the United Kingdom. He worked mainly in poster art, but was also active as a painter, book illustrator and theatre designer.
In 1921 Bevan organised, with Ginner, an exhibition of Un Groupe de Peintres Anglais Modernes at the Galerie Druet in Paris to present their own work and that of Stanislawa de Karlowska, Gilman, and the next generation artists E.M. O'Rourke Dickey, McKnight Kauffer, John Nash, Edward Wadsworth, William Roberts and Ethelbert White.
Harold John Wilde Gilman was a British painter of interiors, portraits and landscapes, and a founder-member of the Camden Town Group.
Edward Alexander Wadsworth was an English artist, most famous for his close association with Vorticism. He painted, often in tempera, coastal views, abstracts, portraits and still-life. He was also an engraver on wood and copper. In the First World War he was involved in transferring dazzle camouflage designs onto ships for the Royal Navy, and after the war he continued to paint nautical themes.
William Patrick Roberts was a British artist.
A Countryman in Town: Robert Bevan and the Cumberland Market Group was held at Southampton City Art Gallery, 26 September – 14 December 2008. It moved to Abbot Hall Art Gallery, Kendal, 13 January – 21 March 2009. 
The Southampton City Art Gallery is an art gallery in Southampton, southern England. It is located in the Civic Centre on Commercial boulevard.
Abbot Hall Art Gallery is a museum and gallery in Kendal, England. Abbot Hall was built in 1759 by Colonel George Wilson, the second son of Daniel Wilson of Dallam Tower, a large house and country estate nearby. It was built on the site of the old Abbot’s Hall, roughly where the museum is today. Before the Dissolution of the Monasteries this was where the Abbot or his representative would stay when visiting from the mother house of St Mary's Abbey, York. The architect is unknown. During the early twentieth century the Grade I listed building was dilapidated and has been restored as an art gallery.
Group X was a short-lived British artistic movement in the years after the First World War. Several of its members – among them Wyndham Lewis – had been part of the Vorticist movement before the War. The group held a single exhibition in 1920; others were planned, but never happened.
In art, neorealism refers to a few movements.
The London Group is a society based in London, England, created to offer additional exhibiting opportunities to artists besides the Royal Academy of Arts. Formed in 1913, it is one of the oldest artist-led organisations in the world. It was formed from the merger of the Camden Town Group, an all-male group, and the Fitzroy Street Group. It holds open submission exhibitions for members and guest artists.
Spencer Frederick Gore was a British painter of landscapes, music-hall scenes and interiors, usually with single figures. He was the first president of the Camden Town Group, and was influenced by the Post-Impressionists.
Francis Vane Phipson Rutter was a British art critic, curator and activist.
Stanisława de Karłowska was a Polish-born artist, who was married to the Camden Town Group painter Robert Bevan.
Eric Forbes-Robertson (1865–1935) was a British figure and landscape painter, the brother of two actors (Sir) Johnston Forbes-Robertson and Norman Forbes (-Robertson).
Unit One was a British grouping of Modernist artists founded by Paul Nash. The group included painters, sculptors and architects, and was active from 1933 to 1935. It held one exhibition, which began at the Mayor Gallery in Cork Street, London, and then went on an extended tour, closing in Belfast in 1935. A book by Herbert Read, Unit One: the modern movement in English painting, sculpture, and architecture, was published at the time of the exhibition. Despite its brief period of activity, the group is regarded as influential in establishing the pre-eminence of London as a centre of modernist and abstract art and architecture in the mid-1930s.
Robert Alexander Polhill "R. A." Bevan (“Bobby”) CBE was a significant figure in British communications and advertising during the mid-20th century. He was the second child of the artists Robert Polhill Bevan and Stanisława de Karłowska and was born at the Bevan house, Horsgate, in Cuckfield, Sussex.
The Crab Tree Club was a nightclub in Greek Street, Soho, London, that was established by the painter Augustus John in April 1914 with the financial support of Thomas Scott-Ellis. John wrote to his friend John Quinn, "We are starting a new club in town called the 'Crab-tree' for artists, poets and musicians... It ought to be amusing and useful at times". The club was a popular meeting place for London bohemians immediately before the First World War who would descend en-masse on the Crab Tree after the Café Royal closed for the night.
Ian Strang, A.R.E., R.E., was a British draughtsman and etcher who specialised in topographical subjects.
Mabel Frances Layng was an English landscape and figure painter.
Mary Godwin (1887-1960) was a British oil painter, water colourist and etcher, who often chose landscapes, interiors, and figures as subjects. She studied at the Women’s Department of King’s College with John Byam Shaw, and at Westminster Technical Institute with Walter Sickert and Harold Gilman. She was influenced by the Camden Town Group, and joined its successor, The London Group (LG) in 1914.
