National Park Service is celebrating its centennial

The National Park Service (NPS) is an agency of the United States federal government that manages all U.S. national parks, many American national monuments, and other conservation and historical properties with various title designations. It was created on August 25, 1916, by Congress through the National Park Service Organic Act and is an agency of the United States Department of the Interior. The NPS is charged with a dual role of preserving the ecological and historical integrity of the places entrusted to its management while also making them available and accessible for public use and enjoyment.

As of 2008 21,989 employees of the NPS oversee 413 units, of which 59 are designated national parks.

The National Park Service is celebrating its centennial in 2016.


National parks and national monuments in the United States were originally individually managed under the auspices of the Department of the Interior. The movement for an independent agency to oversee these federal lands was spearheaded by business magnate and conservationist Stephen Mather, as well as J. Horace McFarland. With the help of journalist Robert Sterling Yard, Mather ran a publicity campaign for the Department of the Interior. They wrote numerous articles that praised the scenic and historic qualities of the parks and their possibilities for educational, inspirational, and recreational benefits. This campaign resulted in the creation of a National Park Service. On August 25, 1916, President Woodrow Wilson signed a bill that mandated the agency "to conserve the scenery and the natural and historic objects and wildlife therein, and to provide for the enjoyment of the same in such manner and by such means as will leave them unimpaired for the enjoyment of future generations." Mather became the first director of the newly formed NPS.

On March 3, 1933, President Herbert Hoover signed the Reorganization Act of 1933. The act would allow the President to reorganize the executive branch of the United States government. It wasn't until later that summer when the new President, Franklin D. Roosevelt, made use of this power. Deputy Director Horace M. Albright had suggested to President Roosevelt that the historic sites from the American Civil War should be managed by the National Park Service, rather than the War Department. President Roosevelt agreed and issued two Executive orders to make it happen. These two executive orders not only transferred to the National Park Service all the War Department historic sites, but also the national monuments managed by the Department of Agriculture and the parks in and around the capital, which had been run by an independent office.
