Who was the first European known to see Victoria Falls?

The Scottish missionary and explorer David Livingstone was the first European known to see Victoria Falls. He arrived at the falls on November 16, 1855, during his expedition across the African continent, and named them in honor of Queen Victoria of the United Kingdom.123

It is important to note that while Livingstone was the first European to document the site, the falls were already well known to the local Lozi people, who referred to them as Mosi-oa-Tunya, meaning "The Smoke That Thunders".2
