Scandinavian inspiration for Shaw (5)
I believe the answer is:
ibsen
(Other definitions for ibsen that I've seen before include "not one for 'All work and no play ...'" , "famous Norwegian" , "6 24 113 [SCAN-DIN-AVIAN] writer" , "'Doll's House' playwright" , "Norwegian author of 'Peer Gynt' etc" .)
