Mather, "he extrapolated his knowledge of human behaviour from consumerism to nationalism in a report which suggested 'applying the Gallup technique to fields of secret intelligence. Eisenhower's Psychological Warfare Board picked up the report and successfully put Ogilvy's suggestions to work in Europe during the last year of the war. Also during World War II David Ogilvy was a notable alumnus of the secret Camp X, located near the towns of Whitby and Oshawa in Ontario, Canada. According to an article on the camp: "It was there he mastered the power of propaganda before becoming king of Madison Avenue. Although Ogilvy was trained in sabotage and close combat, he was ultimately tasked with projects that included successfully ruining the reputation of businessmen who were supplying the Nazis with industrial materials."
