Dr. David Livingstone is a legend among explorers and adventurers, a true example of North Sea strength and Scottish grit. During his incredible life, Livingstone undertook three major expeditions into the Dark Heart of Africa, travelling a phenomenal 29,000 miles, a greater distance than the circumference of the earth. Achieving this in any circumstances is incredibly impressive, but doing so in the 19th century, during the Victorian era when almost nothing was known about the interior of Africa, is astonishing. It is no exaggeration to say that even the very first astronauts to walk on the moon in the 1960s knew more about its surface than Victorian explorers did about the center of Africa: it really was unchartered territory.
