Henrik —, author of stage plays Hedda Gabler and The League of Youth (5)
I believe the answer is:
ibsen
(Other definitions for ibsen that I've seen before include "6 24 113 [SCAN-DIN-AVIAN] writer" , ""Doll's House" dramatist" , "Noted Norwegian playwright" , "not one for 'All work and no play ...'" , "Dramatist, author of Peer Gynt" .)
