The oldest verified World War II veteran in the U.S. passed away Tuesday at the age of 110.

Frank Levingston enlisted in the U.S. Army on Oct. 6, 1942, according to the National Archives, less than one year after Japan’s attack on Pearl Harbor propelled the U.S. into World War II. Levingston has seen 19 presidents hold office during his lifetime.

“He felt the obligation to give to the country whatever he possibly could, and he was very excited about it,” Jee Levingston, Frank’s nephew, told ABC News today. “He gave it his very best.”

Levingston told ABC News that his uncle was born on Nov. 13, 1905, in Cotton Valley, Louisiana, and that both of Frank’s parents died when Frank was very young.
