William John Burchell (23 July 1781 – 23 March 1863) was an English explorer, naturalist, traveller, artist, and author. His thousands of plant specimens, as well as field journals from his South American expedition, are held by Kew Gardens, and his insect collection by the Oxford University Museum.
William John Burchell was born in Fulham, London, the son of Matthew Burchell, botanist and owner of Fulham Nursery, and his wife. His father owned nine and a half acres of land adjacent to the gardens of Fulham Palace. Burchell served a botanical apprenticeship at Kew and was elected F.L.S. (Fellow of the Linnaen Society) in 1803. At about this time, he became enamoured of Lucia Green of Fulham, but faced strong disapproval from his parents when he broached the idea of an engagement.
On 7 August 1805 Burchell at the age of 24 sailed for St. Helena aboard the East Indiaman Northumberland, intending to set up there as a merchant with a partner from London, William Balcombe (1779-1829). After a year of trading, Burchell did not want to continue and dissolved the partnership. Three months later he accepted a position as schoolmaster on the island and later as official botanist.
In 1810 he sailed to the Cape of Good Hope in South Africa on the recommendation of Gen. J.W. Janssens to explore and to add to his botanical collection. Burchell's intended wife had jilted him for the captain of the boat taking her to St. Helena to join him.
Landing at Table Bay on 26 November 1810, after stormy weather had prevented a landing for 13 days, Burchell set about planning an expedition into the interior. He left Cape Town in June 1811.
Burchell travelled in South Africa between through 1815, collecting over 50,000 specimens, and covering more than 7000 km, much over unexplored terrain. He described his journey in Travels in the Interior of Southern Africa, a two-volume work appearing in 1822 and 1824. (It was reprinted in 1967 by C. Struik of Cape Town.) He is believed to have planned a third volume, since the second ends long before he completed his journey. On 25 August 1815 he sailed from Cape Town with 48 crates of specimens aboard the vessel Kate, calling at St. Helena and reaching Fulham on 11 November 1815.
