While memorial services in Memorial Amphitheater are common, the amphitheater has also hosted the funerals of many famous Americans. The first funeral to be held in the amphitheater was that of sculptor Moses Jacob Ezekiel, creator of the Confederate Memorial at Arlington National Cemetery, on March 30, 1921. Other funerals held in the amphitheater since then include those of General of the Armies John J. "Black Jack" Pershing, General of the Air Force Henry H. "Hap" Arnold, Secretary of Defense James Forrestal, and Antarctic explorer and Rear Admiral Richard E. Byrd. A funeral service for the unidentified remains of 30 victims of the September 11 attacks on The Pentagon was held at Memorial Amphitheater in 2002. It was the first time the amphitheater had held such a service since the interment of an unknown member of the armed forces representing Vietnam War dead in 1984.
