Prescott Bush's (Father and Grandfather of two future US Presidents) business interests in Germany suffered after the outbreak of the Second World War. On 20th October, 1942, the United States government seized the assets of the Union Banking Corporation. The shares of the bank were owned by Prescott Bush, E.

Under the Trading with the Enemy Act, the government took over the Union Banking Corporation and the Silesian-American Corporation, a company that had been managed by Prescott Bush and his father-in-law George Herbert Walker.
