I saw this online today and had forgotten the story about looking for Livingstone. During the 19th century there was a great interest in Africa as it was pretty much still unexplored by Europeans. The now famous statement "Doctor Livingstone, I presume?" Hit the headlines after the New York Herald sent Stanley to look for Livingstone.
He discovered him after a long trek through Africa and contracting a couple of diseases. The sad part to this story is that after Stanley found the good doctor, Livingstone did not want to returned to England and continued into the heart of Africa to find the source of the River Nile. Livingstone later died and his body was returned to England for burial.
