Henry Morton Stanley was born in Denbigh, Wales, in 1841. He became a cabin boy and arrived in New Orleans in 1859. He remained in the United States and served in the Confederate Army during the American Civil War.
After the war he became a freelance journalist. In 1866 George Ward Nichols interviewed Wild Bill Hickok about his exploits as a gunfighter. The article appeared in the February, 1867, edition of Harper's New Monthly Magazine. Newspapers such as the Leavenworth Daily Conservative, Kansas Daily Commonwealth, Springfield Patriot and the Atchison Daily Champion quickly pointed out that the article was full of inaccuracies and that Hickok was lying when he claimed he had killed "hundreds of men".
Hickok responded to these articles by giving an interview to Henry Stanley. The article appeared in the St. Louis Missouri Democrat in April 1867. It included the following dialogue: "I say, Mr. Hickok, how many white men have you killed to your certain knowledge?" After a little deliberation, he replied, "I suppose I have killed considerably over a hundred." "What made you kill all those men? Did you kill them without cause or provocation?" "No, by heaven I never killed one man without good cause."
Stanley now joined the New York Herald and in 1868 accompanied an expedition to Abyssina. He also visited Egypt, Palestine, Turkey, Persia and India. On 10th November, 1871, Stanley met David Livingstone in Tanganyika. On his return to the United States he published How I Found Livingstone (1872).
Stanley visited Africa again and after exploring Lake Tanganyika he traced the River Congo to the sea. This journey resulted in the book, Through the Dark Continent. After returning to Britain he became a member of the House of Commons for Lambeth.
Sir Henry Morton Stanley died in 1904.
