The British Institution (in full, the British Institution for Promoting the Fine Arts in the United Kingdom; founded 1805, disbanded 1867) was a private 19th-century society in London formed to exhibit the works of living and dead artists; it was also known as the Pall Mall Picture Galleries or the British Gallery. Unlike the Royal Academy it admitted only connoisseurs, dominated by the nobility, rather than practicing artists to its membership, which along with its conservative taste led to tensions with the British artists it was intended to encourage and support. In its gallery in Pall Mall the Institution held the world's first regular temporary exhibitions of Old Master paintings, which alternated with sale exhibitions of the work of living artists; both quickly established themselves as popular parts of the London social and artistic calendar. From 1807 prizes were given to artists and surplus funds were used to buy paintings for the nation.
The British Institution was founded in June 1805 by a group of private subscribers who met in the Thatched House Tavern in London. A committee was formed, and in September of that year it purchased the lease of the former Boydell Shakespeare Gallery building at 52 Pall Mall, with 62 years remaining, for a premium of £4,500 and an annual ground rent of £125. The British Institution opened at the Pall Mall site on 18 January 1806.
The founding "Hereditory Governors" included Sir George Beaumont, 7th Baronet and Charles Long, 1st Baron Farnborough, both of whom had employed the services of the leading dealer and picture-cleaner William Seguier, and were probably responsible for his appointment as "Superintendent". Seguier later became Surveyor of the King's Pictures and when the National Gallery, London was founded in 1824, was appointed as the first Keeper, holding all three positions until his death in 1843, as well as continuing to run his business. Above Seguier the Institution had a Keeper, a role given to a series of engravers. The Superintendent was responsible for organizing and hanging the shows, a role that inevitably gave rise to grumbling and worse from artists – at the Royal Academy a committee was responsible for the hang, which allowed someone else to be blamed, but Seguier had no such opportunity to share the blame. In 1833 John Constable wrote with heavy irony of having received a visit in his studio from "a much greater man than the King—the Duke of Bedford—Lord Westminster—Lord Egremont, or the President of the Royal Academy — "MR SEGUIER"." When in 1832 two pictures by Richard Parkes Bonington, who had been dead only four years, were included in an "Old Masters" exhibition, Constable (who was twenty-six years older than Bonington) wrote that Seguier was "carrying on a Humbugg".
