In the late 18th Century British explorer David Livingstone set off for Africa to find the source of the Nile after previously undertaking African expeditions in the 1840s and 1850s.
 
	
	
	
		
		
		
		
	
	
Livingstone
 
He set off to try and find the Nile's source in 1866.
 
However, during his expedition, he went missing for a few years.  He completely lost contact with the outside world.  Only one of his 44 letter dispatches made it to
 Zanzibar. One surviving letter to Horace Waller, made available to the public in 2010 by its owner Peter Beard, reads: "I am terribly knocked up but this is for your own eye only, ... Doubtful if I live to see you again ..."
 
Desperate to solve the mystery as the the great explorer's whereabouts, in 1869 the New York Herald newspaper sent out the American, Henry Morton Stanley, to try and find him.  At the time the United States and Great Britain were not on friendly terms.
 
Stanley found Livingstone in the town of 
Ujiji on the shores of Lake Tanganyika on 27th October 1871.  Stanley was not too sure how the Briton would react coming face to face with an American but he greeted the explorer with the now famous line "Dr Livingstone, I presume?"  In reply, Livingstone said "Yes, and I feel thankful that I am here to welcome you."  It seems that Stanley's statement was tongue-in-cheek: apart from him, Livingstone was the only white man around for hundreds of miles.
 
The two men each doffed their hat and shook hands.
 
Despite Stanley's urgings, Livingstone would not leave Africa until his mission was complete. He  died in that area in Chief Chitambo's village at Ilala southeast of Lake Bangweulu in present-day Zambia on 1st May 1873 from 
malaria and internal bleeding caused by dysentery. He took his final breaths while kneeling in prayer at his bedside.
