"Harriman's banking business was the main Wall Street connection for German companies and the varied U.S. financial interests of Fritz Thyssen; who was a financial backer of the Nazi party until 1938. The Trading With the Enemy Act (enacted on October 6, 1917)[4] classified any business transactions for profit with enemy nations as illegal, and any funds or assets involved were subject to seizure by the U.S. government. The declaration of war on the U.S. by Hitler led to the U.S. government order on October 20, 1942 to seize German interests in the U.S. which included Harriman's operations in New York City.
The Harriman business interests seized under the act in October and November 1942 included:[citation needed]
Union Banking Corporation (UBC) (from Thyssen and Brown Brothers Harriman)
Holland-American Trading Corporation (from Harriman)
Seamless Steel Equipment Corporation (from Harriman)
Silesian-American Corporation (this company was partially owned by a German entity; during the war the Germans tried to take full control of Silesian-American. In response to that, the American government seized German-owned minority shares in the company, leaving the U.S. partners to carry on the portion of the business in the United States.)
The assets were held by the government for the duration of the war, then returned afterward; UBC was dissolved in 1951."
