Who named Lake Nyasa in Tanzania?

Like Stanley, I presumed the correct answer was Livingstone...

mitch, I understand your answer to Blooply, but I agree that it would have been nice to have that laid out in the answer, since it was about name

Blooply, He was known to have had a respect for indigenous peoples.He was probably one of those rare explorers who asked the locals what they called it.

Real good question and I got it right!!
