The Arlington Memorial Amphitheater at Arlington National Cemetery, near the center of the Cemetery, is the home of the Tomb of the Unknowns where Unknown American Servicemembers from World War I, World War II, and Korea are interred. This site has also hosted the state funerals of many famous Americans, such as General of the Armies John J. "Black Jack" Pershing, General of the Air Force Henry H. "Hap" Arnold, the Unknown Soldiers, and five victims of the September 11 attacks, as well as annual Memorial Day and Veterans Day ceremonies. Every American President of the 20th and 21st centuries has presided over holiday gatherings at this site.

Judge Ivory Kimball worked during several sessions of Congress as the department head of the Grand Army of the Republic in the District to get a bill through Congress to build the Amphitheatre. The bill finally went through in President Theodore Roosevelt's Administration
