'When I was an undergraduate, some years ago, I read a comment on biography by Sir Lewis Namier, the magisterial historian of eighteenth century British politics. Namier thought that someone embarking on a biography was no better qualified for the task than a woman who applied for the position of minding children and said in support of her application that she herself had once been a child. No doubt with the advancement of so many academic disciplines and the multi-skilling of so many academics, Namier’s dismissal of biography is now out of date for most biographers. But not so in my case. When, therefore, I was commissioned to write a biography of Sir John Gorton (2002), a chapter on Sir Robert Askin (2006) and a long entry on Harold Holt in the Australian Dictionary of Biography (1996), I realised that my immediate problem was myself. Very simply, my qualifications, let alone my experience, did not equip me for the task.' (Introduction)
