Introduction: The Booker Prize (now The Booker Prize for Fiction) is one of the world's most prestigious literary awards. A select few authors have managed to win it more than once.
Information Booster:
· J.M. Coetzee won twice: for Life & Times of Michael K (1983) and Disgrace (1999).
· Peter Carey won twice: for Oscar and Lucinda (1988) and True History of the Kelly Gang (2001).
· Hilary Mantel won twice: for Wolf Hall (2009) and Bring Up the Bodies (2012).
· Douglas Stuart won the Booker Prize once, for his debut novel Shuggie Bain (2020). He has not won it a second time.
Additional Knowledge: The other multiple winners are Margaret Atwood (though one was the special "Lost Man Booker"), and since 2023, the rules have changed to allow any previously winning author to win again. As of now, Douglas Stuart is a single winner.
