Who went to Stockholm in 1993 and got the Nobel Prize in Literature?: In a 1994 interview, Toni Morrison says it was Chloe Wofford

Q: It must have been fulfilling, in 1970, to see your name on the cover of “The Bluest Eye.”

A: I was upset. They had the wrong name: Toni Morrison. My name is Chloe Wofford. Toni’s a nickname.

Q: Didn’t you know your publisher, Holt, was going to use the name?

A: Well, I sort of knew it was going to happen. I was in a daze. I sent it in that way because the editor knew me as Toni Morrison.

Q: So you achieved fame misnamed?

A: Tell me about it! I write all the time about being misnamed. How you got your name is very special. My mother, my sister, all my family call me Chloe. It was Chloe, by the way, who went to Stockholm last year to get the Nobel Prize.
