Henry M. Stanley in 1871 found David Livingstone, the missing missionary, in Africa. He asked the famous question, “Dr. Livingstone, I presume?” Dr. Livingstone, missing for six years, was trying to find the source of the Nile. Most people assumed he had died. Stanley was sent by the New York Herald to find Livingstone. After their meeting Livingstone remained in Africa but died about 2.5 years later. Older children can read books by Livingstone and by Stanley at: Project Gutenberg.
