David Livingstone (19 March 1813 â 1 May 1873) was a Scottish Congregationalist pioneer medical missionary with the London Missionary Society and an explorer in Africa.
Bingham's discovery was published in the April 1913 issue of National Geographic magazine, bringing the mountaintop citadel to the world's attention.
