David John Cawdell Irving an English author and Holocaust denier who has written on the military and political history of World War II, with a focus on Nazi Germany. His works include The Destruction of Dresden (1963), Hitler's War (1977), Churchill's War (1987) and Goebbels: Mastermind of the Third Reich (1996). In his works, he argued that Adolf Hitler did not know of the extermination of Jews or, if he did, opposed it. Though Irving's revisionist views of World War II were never taken seriously by mainstream historians, he was once recognised for his knowledge of Nazi Germany and his ability to unearth new historical documents.
