Sir Joseph Dalt Hooker (1817-1911), English botanist and explorer of the Antarctic. He also conducted scientific studies in New Zealand, in the Himalayas of Asia, in North Africa, and in the Rocky Mountains of North America. Born in Halesworth, England, Hooker was the son of English botanist Sir William Jackson Hooker. Like his father, the younger Hooker became interested in the study of plants. He also studied medicine at the University of Glasgow and became a doctor.
In 1839 Hooker joined Sir James Clark Ross’s Antarctic expedition as a botanist and assistant medical officer. The expedition made stops at the Kerguelen Islands of the southern Indian Ocean, at New Zealand, at the island of Van Diemen’s Land (present-day Tasmania), and at islands of the Southern Ocean. In all of these places, Hooker undertook comprehensive studies of plants and collected thousands of specimens, many of them new to science. On Tasmania, he discovered a new species of eucalyptus tree. Hooker returned to England with the Ross expedition in 1843; and over the next four years he published the results of his scientific research in Flora Antarctica (1844-1847).
In 1846 and 1847 Hooker served as botanist with the Geological Survey of Great Britain, and in the late 1840s his pursuit of botanical knowledge took him to the Himalayas of Nepal and what is now Bangladesh. After 1865 Hooker succeeded his father as director of England’s extensive Kew Gardens, also known as the Royal Botanical Gardens, near London. In connection with his work at Kew Gardens, he made scientific expeditions to the Middle East, the Atlas Mountains of Morocco, and the Rocky Mountains of the western United States. Hooker drew upon his worldwide studies to support the still-controversial theories of British scientist Charles Darwin regarding evolution and the origins of life on earth. Hooker also published the three-volume Geneara Plantarum (1862-1883) and the seven-volume Flora of British India (1875-1897). He was knighted in 1877.
