Ira “Ike” Schab, a World War II Navy veteran and one of the few remaining survivors of the 1941 Pearl Harbor attack, has passed away at the age of 105.

His daughter, Kimberlee Heinrichs, confirmed to The Associated Press that Schab peacefully died at home early on Saturday, with her and her husband by his side.

With Schab’s passing, the number of survivors from the fateful day that claimed over 2,400 American lives and drew the United States into World War II has dwindled to roughly a dozen.

At the time of the attack, Schab was a 21-year-old sailor. Although he seldom discussed the harrowing event for many years, he became more open about it in his later life.

Recognizing the importance of preserving the memory of that day and the diminishing number of survivors, Schab made it a priority to journey from his home in Beaverton, Oregon, to attend the annual commemoration at the Pearl Harbor military base in Hawaii.

“To pay honor to the guys that didn’t make it,” he said in 2023.

For last year’s commemoration, Schab spent weeks building up the strength to be able to stand and salute.

But this year he did not feel well enough to attend, and less than three weeks later, he passed away.

Born on Independence Day in 1920 in Chicago, Schab was the eldest of three brothers.

He joined the Navy at 18, following in the footsteps of his father, he said in a February interview for Pacific Historic Parks.

On what began as a peaceful Sunday, Dec. 7, 1941, Schab, who played the tuba in the USS Dobbin’s band, was expecting a visit from his brother, a fellow service member assigned to a nearby naval radio station. Schab had just showered and donned a clean uniform when he heard a call for fire rescue.

He went topside and saw another ship, the USS Utah, capsizing. Japanese planes roared through the air.

“We were pretty startled. Startled and scared to death,” Schab recalled in 2023. “We didn’t know what to expect, and we knew that if anything happened to us, that would be it.”

He scurried back below deck to grab boxes of ammunition and joined a daisy chain of sailors feeding shells to an anti-aircraft gun above.

His ship lost three sailors, according to Navy records. One was killed in action, and two died later of fragment wounds from a bomb that struck the stern. All had been manning an anti-aircraft gun.

Schab spent most of the war with the Navy in the Pacific, going to the New Hebrides, now known as Vanuatu, and then the Mariana Islands and Okinawa, Japan.

After the war he studied aerospace engineering and worked on the Apollo spaceflight program as an electrical engineer for General Dynamics, helping send astronauts to the moon.

Schab’s son also joined the Navy and is a retired commander.

Speaking at a 2022 ceremony, Schab asked people to honor those who served at Pearl Harbor.

“Remember what they’re here for. Remember and honor those that are left. They did a hell of a job,” he said. “Those who are still here, dead or alive.”
