War Powers Act of 1941

The War Powers Act of 1941, also known as the First War Powers Act, was an U.S. Executive Branch.[1]

The act gave the President enormous authority to execute World War II in an efficient manner. The president was authorized to reorganize the executive branch, independent government agencies, and government corporations for the war cause. With the act, the President was allowed to censor mail and other forms of communication between the United States and foreign countries. The act and all changes created by its power were to remain intact until six months after the end of the war at which time, the act would become defunct.[1]

Three months after passing the first, the Second War Powers Act was passed on March 27, 1942. This further strengthened the executive branch powers towards executing World War II. This act allowed the acquisition, under condemnation if necessary, of land for military or naval purposes. Some provisions of the Hatch Act of 1939 were also suspended which reduced naturalization standards for aliens within the U.S. Armed Forces. In addition, it created methods for war-related production contracting along with adjusting several other aspects of government affairs.[1] The Second War Powers Act repealed the confidentiality of census data, allowing the FBI to use this information to round up Japanese-Americans.[2]

Under Secretary of War Robert P. Patterson retrospectively delegated his authority from the President under the War Powers Act of 1941 to Leslie Groves for the Manhattan Project. The authority, given in a memorandum to Groves dated April 17, 1944, was retrospective to September 1, 1942. The written delegation was only given in 1944 when Groves deputy Kenneth Nichols was about to sign a large contract with Du Pont, and it was found that he only had a low delegated authority, as Nichols' higher authority for the Manhattan Project had only been given verbally.[3]
