The Linnean Society of London is a learned society dedicated to the study and dissemination of information concerning natural history, evolution, and taxonomy. It possesses several important biological specimen, manuscript and literature collections, and publishes academic journals and books on plant and animal biology. The society also awards a number of prestigious medals and prizes. A product of the 18th-century enlightenment, the Society is the oldest extant biological society in the world and is historically important as the venue for the first public presentation of the theory of evolution by natural selection on 1 July 1858. The patron of the society was Queen Elizabeth II. Honorary members include: King Charles III of Great Britain, Emeritus Emperor Akihito of Japan, King Carl XVI Gustaf of Sweden (both of the latter have active interests in natural history), and the eminent naturalist and broadcaster Sir David Attenborough. History Founding The Linnean Society was founded in 1788 by botanist Sir James Edward Smith. The society takes its name from the Swedish naturalist Carl Linnaeus, the 'father of taxonomy', who systematised biological classification through his binomial nomenclature. He was known as Carl von Linné after his ennoblement, hence the spelling 'Linnean', rather than 'Linnaean'. The society had a number of minor name variations before it gained its Royal Charter on 26 March 1802, when the name became fixed as "The Linnean Society of London". In 1802, as a newly incorporated society, it comprised 228 fellows. It is the oldest extant natural history society in the world. Throughout its history the society has been a non-political and non-sectarian institution, existing solely for the furtherance of natural history. The inception of the society was the direct result of the purchase by Sir James Edward Smith of the specimen, book and correspondence collections of Carl Linnaeus. When the collection was offered for sale by Linnaeus's heirs, Smith was urged to acquire it by Sir Joseph Banks, the eminent botanist and president of the Royal Society. Five years after this purchase Banks gave Smith his full support in founding the Linnean Society, and became one of its first Honorary Members. Prominent members The society has numbered many prominent scientists amongst its fellows. One such was the botanist Robert Brown, who was librarian, and later president (1849–1853); he named the cell nucleus and discovered Brownian motion. In 1854 Charles Darwin was elected a fellow; he is undoubtedly the most illustrious
