From the outbreak of the First World War Wiegand worked to influence American public opinion in favour of Germany and against the Allies. In 1915 he published Current misconceptions about the war, containing an interview with the German crown prince, and several essays, and a series of letters, all presenting the German point of view. Wiegand was the first United States reporter allowed to interview Crown prince Wilhelm. That interview was also the first foreign interview given by a German noble since the outbreak of World War I. William E. Dodd, US ambassador to Germany during the Roosevelt administration later described him as a "very strongly pro-German representative through the Great War" Karl von Wiegand was the father of journalist and abstract painterCharmion von Wiegand.
Interwar career
He was one of the Hearst Press reporters on at least two of the Graf Zeppelin flights, usually accompanying fellow Hearst reporter Lady Hay Drummond-Hay. Wiegand was the first American journalist to interview Hitler, having first met him in 1921 while he was only a minor malcontent in post-World War I Munich. He was one of the first journalists to take Hitler seriously, and his story was published on November 12, 1922, a year before the Beer Hall Putsch. As such, Wiegand provided the first introduction Americans had to Hitler. He referred to him as the "German Mussolini", and expressed genuine concern about his popularity, writing "The shadow of the Fascisti is arising in Germany. Whether what is yet only a shadow will clothe itself in the flesh, blood and spirit of the German Mussolini, depends on a number of things." He also emphasized his "man of the people" qualities, his charisma, and his electrifying speaking ability. He pegged him as a potentially great leader, saying "Hitler has the earmarks of a leader. Whether it be merely a band or a great movement, only the future will tell."
A month after Germany invaded France in World War II, Wiegand secured an interview with Hitler and published his report "Europe for the Europeans: Adolf Hitler on the international situation during the war in France; An interview granted to Karl v. Wiegand, Führer's Headquarters, June 11, 1940". Later, Lady Drummond-Hay and Wiegand were interned in a Japanese camp in Manila, Philippines. When they were set free in 1943, she was very ill. They returned to the United States, but during their stay in New York Drummond-Hay died of coronary thrombosis in the Lexington Hotel. After her cremation Karl brought her ashes back to the United Kingdom. He died of pneumonia in Zurich in 1961 at the age of 86.
