New Zealand historian Joel Hayward - who caused a furore with a 1993 thesis that questioned the validity of Holocaust history - is now a senior academic at the heart of the British defence Establishment.
Dr Hayward, 44, is now dean of the Royal Air Force College atCranwell, where Prince William is undergoing pilot training, the Jewish Chronicle reported.
The London-based publication, the world's oldest Jewish paper, said Dr Hayward was appointed last year after two years as head of the air power studies division created by the RAF and King's College, London.
He has lived and worked in Britain since 2004, first teaching strategy at the Joint Services Command and Staff College.
Dr Hayward was at the centre of a bitter controversy in 1993 when there were public calls for Canterbury University to revoke his MA, based on a thesis entitled "The Fate of Jews in German Hands: An Historical Inquiry into the Development and Significance of Holocaust Revisionism".
The 360-page document, which won praise from Holocaust-denier David Irving, alleged that there was never an official Nazi policy to exterminate Jews in gas chambers and questioned whether six million Jews were killed.
Irving, recently jailed in Austria over Holocaust-denial charges, described Dr Hayward as "New Zealand's leading Holocaust historian".
The university ordered an official inquiry into the thesis, and in 2000 described it as "seriously flawed" and said its conclusions about the Holocaust were "perverse and unjustified".
Dr Hayward apologised and withdrew his conclusions.
He said: "It was so long ago. Life is a learning process and one learns from one's mistakes as a young man."
