RESTORE Act: The RESTORE Act (the Resources and Ecosystems Sustainability, Tourist Opportunities, and Revived Economies of the Gulf Coast States Act) is a United States federal statute that was signed into law by President Barack Obama on July 6, 2012.  It was enacted by the 112th United States Congress as an amendment to the “Moving Ahead for Progress in the 21st Century” bill, a far-reaching transportation bill that included many other provisions.

Hallvard Graatop: Hallvard Graatop was a Norwegian rebel leader who fought against Erik of Pomerania.  The name "Graatop", meaning "Gray-top" is probably a "nom de guerre", possibly referring to gray hair or a gray hood (as a wanted outlaw, he may have concealed his face).  Graatop's true identity is unknown.  Popular stories in the Telemark area claim him to be "Lord" Hallvard Torbjørnsen of Roaldstad (later known as Vrålstad) farm, grandfather of Aslaug Torbjørnsdatter Vrålstad (herself an ancestor of Queen Sonja of Norway and Andrew Volstead), but this is disputed (see "Controversy", below).

The Act was reauthorized in 1950 , but in 1951, it and the Economic Cooperation Act were succeeded by the Mutual Security Act, and its newly created independent agency, the Mutual Security Administration, to supervise all foreign aid programs, including both military assistance programs and non-military, economic assistance programs that bolstered the defense capability of U.S. allies.

On November 3, 1961, President John F. Kennedy signed the Act and issued Executive Order 10973, detailing the reorganization.
