David Livingstone (19 March 1813 – 1 May 1873) was a British Congregationalist pioneer medical missionary with the London Missionary Society and explorer in central Africa. He was the first European to see Mosi-oa-Tunya (Victoria Falls), to which he gave the English name in honour of his monarch, Queen Victoria. He is the subject of the meeting with H. M. Stanley, which gave rise to the popular quotation, "Dr Livingstone, I presume?"
Perhaps one of the most popular national heroes of the late-nineteenth century in Victorian Britain, Livingstone had a mythic status, which operated on a number of interconnected levels: that of Protestant missionary martyr, that of working-class "rags to riches" inspirational story, that of scientific investigator and explorer, that of imperial reformer, anti-slavery crusader and advocate of commercial empire.
