The Office of Alien Property Custodian was an office within the government of the United States during World War I and again during World War II, serving as a custodian to property that belonged to US enemies. The office was created in 1917 by Executive Order 2729-A under the Trading with the Enemy Act of 1917 (TWEA) in order to "assume control and dispose of enemy-owned property in the United States and its possessions."[1][2]
