He found Livingstone (7)
I believe the answer is:
stanley
'he found livingstone' is the definition.
(I've seen this in another clue)
This is the entire clue.
(Other definitions for stanley that I've seen before include "Falkland Islands city" , "Type of knife" , "island capital" , "Falklands capital; --- Baldwin, PM" , "African explorer; Falklands town" .)
