Berkowitz was in the Army, as a private first class, from 1963-1965. He served as a microwave technician in Japan, first at Camp Tomlinson in Kashiwa, then in Okinawa. "It was great duty," he said.

Berkowitz was originally from Belgium and came to the United States when he was 12. His wife Esther came to the U.S. when she was two. The two were visiting Washington from Brooklyn.

"I find Arlington a very inspiring place," Esther said.

While Esther said they didn't know anyone who might be buried in the cemetery -- she did say she knew some that have died in World War II, "but not as Soldiers -- our families," she said.

Albert confirmed -- both he and Esther had escaped from Europe during the war, though not all in their families had been so lucky.

Corey O'Dell, of Round Rock, Texas, was also visiting the cemetery and passed through the chapel with his mother, Kathryn and brother, Ethan -- he clutched a World War II history book in his hand.

"I do have some WWI books at home and I study a lot about WWII," he said, adding his take on Buckles -- "He was a pretty good man."

Buckle's casket remained in the chapel at the cemetery until about 4 p.m. Tuesday, when the Old Guard took it to the burial site in the cemetery. Buckles was buried with full military honors in section 34 of the cemetery, within sight of Gen. John "Black Jack" Pershing, leader of the American Expeditionary Forces in World War I.
