1. David Livingstone (1813-1873) was a Scottish doctor and missionary. He dedicated his life to exploring Central Africa. In 1840, he made his first expedition to Africa, including crossing the Kalahari Desert in 1849.

2. Story: Livingstone returned to the African continent in 1864. When he went to the interior of Africa, he heard no news from the explorer. For six years, Livingstone lost contact with the outside world. There were various rumors circulating at the time.

3. The boss of the American "New York Herald" gave his reporter Henry Stanley an almost impossible task to lead an expedition to the African continent to find Livingstone. After nearly eight months of travel, Stanley's expedition approached Ujiji, a small village on the shore of Lake Tanganyika, on November 10, 1871. There they found Livingstone.

4. The famous greeting when they met, "You are Dr. Livingstone, if I guess correctly?" This famous quote is recorded in the Encyclopedia Britannica and the Oxford Dictionary of National Biography. This quote is only famous because of its tongue-in-cheek humor: Dr. Livingstone was the only white man seen within hundreds of miles. Stanley also stated in his book that the first sentence he said at that time was because the scene was a bit embarrassing. He finally found the person he was looking for. He wanted to go up and hug him, but he did not dare to do so because of his pride.
