And, 150 years ago today, after going missing for six years, the Scottish medical missionary and explorer of Africa, Dr. David Livingstone, was found by journalist Henry Stanley (pictured), who famously asked upon meeting him, Dr. Livingstone, I presume?
One of the most popular national heroes of late 19th-century Britain, the Congregationalist anti-slavery preacher (Livingstone) was one of the first Westerners to make a transcontinental journey across Africa.
Livingstone preached a Christian message but did not force it on unwilling ears; he understood the ways of tribal chiefs and successfully negotiated passage through their territory by traveling light, and being hospitably received and aided by locals. His fame as an explorer and his obsession with discovering the sources of the River Nile was founded on the belief that if he could solve that age-old mystery, his fame would give him the influence to end the East African Portuguese and Arab-Swahili slave trade.
