Robert Fay was serving on the Western Front during WWI when he came up with the idea of a time bomb design that disabled rudders on munitions ships. In an American harbour, the explosive would be installed on the rudder using a small boat. His superiors liked the idea and after finding out about his time in America set him up with a fake British passport under the name of H. A. Kearling and $4,000 (US$ 127,000 in 2025). He arrived in New York City on April 23, 1915.
He was assigned German Foreign Office military attaché Franz von Papen as his handler. Working with Paul Daeche, Walter E. Scholz, Otto Wolpert, Max Breitung and Dr. Herbert O. Kienzle they tried to buy explosives. They eventually made contact with a German-American chemist who was secretly working as a double agent for the U.S. Secret Service. They set up a sting operation offering to provide the explosives, eventually arresting Fay, Scholz, Kienzle, and Daeche on October 24, 1915.
In 1916, a federal court sentenced Robert Fay to 8 years in prison over the plot. Scholz was sentenced to four years in prison, and Daesch was sentenced to two years in prison.[6]
