The Joseph Hooker Correspondence Project is conserving, digitising, transcribing and making available online the personal and scientific correspondence of Joseph Hooker (1817-1911), an important - but often overlooked - 19th century naturalist and explorer. He was the leading botanist of his day, pioneered the discipline of geographical botany, and served as President of the Royal Society from 1873-1878 and as Director of the Royal Botanic Gardens, Kew for twenty years (1865-1885).
