I love poetry a great author we learned about in College Literature was English poet Philip Larkin. 
I believe his pen name was Brunette Coleman and he was known for parody
Yes Philip did use the pseudonym Brunettee Coleman a lot of writers did do you think it was to keep them undercover.
Possibly.  Especially if they wrote about controversial subjects
He would always say he liked to surround his poems based on emotions and places and relationships, I thought about doing writing but going under another name.
