The foundation of the society began with a meeting of "gentlemen and friends of entomological science", held on 3 May 1833 in the
British Museum convened by
Nicholas Aylward Vigors with the presidency of
John George Children. Those present were the Reverend
Frederick William Hope,
Cardale Babington,
William Yarrell,
John Edward Gray,
James Francis Stephens,
Thomas Horsfield,
George Thomas Rudd and
George Robert Gray. Letters of
Adrian Hardy Haworth,
George Bennett and
John Curtis were read where they expressed their regrets to be unable to attend the meeting. They decided that a society should be created for the promotion of the science of entomology in its various branches and it should be called the Entomological Society of London. J. G. Children, F. W. Hope, J. F. Stephens, W. Yarrell and G. Rudd were elected to form a committee, with G. R. Gray as secretary. J. G. Children became the first president and
William Kirby (1759–1850) was made honorary president for life. The real date of the foundation of the society was more probably on 22 May 1833, when the members met in
Thatched House Tavern, on St James's Street. During this meeting,
George Robert Waterhouse (1810–1888) was elected librarian and curator of the insects and records. As of this meeting, foreign honorary members were elected:
Johann Cristoph Friedrich Klug (1775–1856),
Wilhem de Haan (1801–1855),
Victor Audouin (1797–1841),
Johann Ludwig Christian Gravenhorst (1777–1857),
Christian Rudolph Wilhelm Wiedemann (1770–1840),
Carl Eduard Hammerschmidt (1800–1874) and
Alexandre Louis Lefèbvre de Cérisy (1798–1867).
William Blandell Spence (1813–1900) received the task of maintaining of the relations with continental entomologists. The society started to assemble a library, an early addition being the personal library of Adrian Hardy Haworth (1767–1833), purchased by
John Obadiah Westwood (1805–1893) on behalf of the society. The insect collection also increased. In September 1834, the society numbered 117 honorary members and 10 full members. Women were allowed membership and benefited from the same rights as the men. A publication commenced in November 1834 under the title
Transactions of the Entomological Society of London. Secretary G. R. Gray resigned in the same year then and was replaced by J. O. Westwood. Under the impulse of this last entomologist, who had many functions, the society made great strides. It was in particular attended regularly by
Charles Darwin (1809–1882) on his return from the voyage on
H.M.S. Beagle: he became a member of the council and vice-president in 1838. J. O. Westwood left his functions in 1848 and was replaced by
Edward Doubleday (1810–1849) and
William Frederick Evans. They in their turn were soon replaced. In 1849, a secretary charged to collect the minutes of the meetings was named in the person of
John William Douglas (1814–1905), a position he kept until 1856. He was assisted in 1851–1852 by
Henry Tibbats Stainton (1822–1892), in 1853-1854 by
William Wing (1827–1855), in 1855-1856 by
Edwin Shepherd who then replaced J.W. Douglas in his position.
Edward Wesley Janson (1822–91), a natural history agent, publisher and entomologist was Curator of the Entomological Society collections from 1850 to 1863 and librarian from 1863 to 1874.
Edward Mason Janson (1847–1880) took over the post of curator from
Frederick Smith (1805–1879) who then left to work in the British Museum. H. T. Stainton, who was involved more and more in the life of the society, seemed to have some problems working with E. M. Janson. He was replaced by W. Wing in 1852. In this year, the society moved from its building at 17, Old Bond Street to 12, Bedford Row. The following year, three of the four most responsible for the society were replaced: Edward Newman (1801–1876) took the place of J. O. Westwood as president, Samuel Stevens (1817–1899) took the place of W. Yarrell as treasurer and W. Wing the place of H. T. Stainton as secretary. In 1885
Queen Victoria granted the society its
royal charter. In 1933, the society's centenary year, King
George V granted it the privilege of adding the word "Royal" to its title, making it the Royal Entomological Society. ==Structure and activities==
