Musical craftsman, poet, dramatist and novelist (6,9)
I believe the answer is:
oliver goldsmith
'poet dramatist and novelist' is the definition.
(18th-century writer)
'musical craftsman' is the wordplay.
'musical' becomes 'oliver' (musical based on Oliver Twist).
'craftsman' becomes 'goldsmith' (someone who works with gold).
'oliver'+'goldsmith'='OLIVER GOLDSMITH'
(Other definitions for oliver goldsmith that I've seen before include "Irish author" , "Irish writer" .)
