Sir Joseph Dalton Hooker (1817–1911),
English naturalist. Interested chiefly in the
origin and development of plants, he made frequent scientific
trips to various parts of the
world, becoming an
authority on facts and problems of
plant distribution. He influenced
English naturalist and author Charles
Darwin (1809–1882) to publish his theories on species development.
