Henry Morton Stanley

Stanley, on an expedition funded by the New York Herald, found the missing missionary David Livingstone at Ujiji on Lake Tanganyika. The meeting produced the famous greeting 'Dr. Livingstone, I presume?' and renewed public interest in African exploration.

Stanley circumnavigated Lake Victoria in a boat, proving it was a single large lake and not a series of smaller lakes. This confirmed it as the primary source of the Nile, resolving a major geographical debate.

Stanley led an expedition into the Congo Basin on behalf of King Leopold II of Belgium. He established trading stations, signed treaties with local chiefs, and surveyed the Congo River, laying the groundwork for the Congo Free State.

Stanley led a large expedition to rescue Emin Pasha, a German governor in Equatoria. The expedition crossed central Africa, faced starvation and disease, and resulted in the deaths of hundreds of porters, but successfully reached Emin Pasha.
