Robert T. Westbrook is an American writer. He was born to columnist Sheilah Graham five years after the death of her lover F. Scott Fitzgerald. Graham claimed Robert's biological father was Trevor Cresswell Lawrence Westbrook, a British businessman whom she divorced in 1946.
After Graham's death in 1988, British philosopher A.J. Ayer came forward to say he was the father of Robert's older half-sister Wendy and that Robert's biological father was most likely the Hollywood actor Robert Taylor. Westbrook was raised in Los Angeles until his teen years, when his mother moved Robert and Wendy to New York City. Robert attended the progressive Putney School and Columbia College.
