David Livingstone

David Livingstone (19 March 1813 – 4 May 1873) was a Scottish Presbyterian pioneer medical missionary with the London Missionary Society and explorer in central Africa. He was the first European to see Victoria Falls, which he named in honour of the reigning monarch. He is the subject of the meeting with H. M. Stanley, which gave rise to the popular quotation, "Dr Livingstone, I presume?"
