'multi-talented fellow' is the definition.
I can't tell whether this defines the answer.

'devised amnesia scanner' is the wordplay.
'devised' indicates an anagram.
'amnesia'+'scanner'='amnesiascanner'
'amnesiascanner' with letters rearranged gives 'RENAISSANCE MAN'.

Can you help me to learn more?

(Other definitions for renaissance man that I've seen before include "All-rounder" , "Person with many talents or interests" , "Wide-ranging intellectual" , "Catholic intellectual" .)
