 From the lede:  
 * Irving's reputation as a historian was discredited after he brought an unsuccessful libel case against the American historian Deborah Lipstadt and Penguin Books.[4]  
 * For example, Sir John Keegan, in "The Battle for History: Refighting World War Two" (Hutchinson, London, 1996), states: "The most valuable of books in this category [WWII biographies], however, in my view, is one that has been called "the autobiography Hitler did not write"  David Irving's Hitler's War...No historian of the Second World War can afford to ignore Irving."'' 

 My question: How is the second sentence an example of the first?  It seems to be completely unrelated to it.  First we're saying his reputation has been discredited, then we're giving him a glowing endorsement from Keegan.  Maybe they should be reversed, to show that he once had a decent reputation, and how and when it disintegrated.
