Konstantin Dumba was involved in schemes to sabotage the U.S. munitions industry and admitted he had sent a letter to be delivered to the Foreign Minister in Vienna.
Konstantin (Theodor) (from 1917, Graf von) Dumba (17 June 1856  6 January 1947), was an Austro-Hungarian diplomat serving as its last accredited Ambassador to the United States and famous for having been expelled during World War I following accusations of espionage. However, a much more serious incident erupted in early September 1915 when media reported that Dr. Dumba had been involved in schemes to sabotage the U.S. munitions industry. On 5 September, the news broke that he had admitted to giving James Francis Jewell Archibald, an American news correspondent, a letter for delivery to Foreign Minister Baron Burian von Rajecz in Vienna.
