Career
In 1920, Spanknöbel was ordained as a minister in the Seventh-day Adventist Church in Würzburg. He was admitted to the US as a minister in 1929, but his relationship with religion was dubious while he was in the country. Spanknöbel was a member of the Free Society of Teutonia and an employee of the Ford Motor Company. Initial support for American fascist organizations came from Germany. In May 1933, NaziDeputy FührerRudolf Hess gave Spanknöbel authority to form an American Nazi organization. Shortly thereafter, with help from the German consul in New York City, Spanknöbel formed the Friends of New Germany by merging two older organizations in the United States— the Society of American Friends of Germany and the Free Society of Teutonia; which were both small groups with only a few hundred members each. The Friends of New Germany was headquartered in Yorkville, Manhattan, but had a strong presence in Chicago. The organization led by Spanknöbel was openly pro-Nazi, and engaged in activities such as storming the German languageNew Yorker Staats-Zeitung with the demand that Nazi-sympathetic articles be published. He attempted to infiltrate and influence other non-political German-American organizations, such as the United German Societies. One of the Friends' early initiatives was to counter, with propaganda, a Jewishboycott of businesses in the heavily German neighborhood of Yorkville. In an internal battle for control of the Friends, Spanknöbel was ousted as leader and subsequently ordered to be deported in October 1933 because he had failed to register as a foreign agent. At the same time, Congressman Samuel Dickstein's investigation concluded that the Friends represented a branch of German dictator Adolf Hitler's Nazi Partyin America. After a U. S. Federal arrest warrant was issued, Spanknöbel boarded the S.S. Europaocean liner bound for Bremen on 29 October. Back in Germany, Spanknöbel reportedly became a director of the Propaganda School for Germans Living Abroad. In 1942, a company called Vereinigte Leder- und Lederwarenfabriken Heinz Spanknöbel & Co. was founded in Hohenbruck near Königgrätz in then Sudetenland.
