Moore did not attend college when he graduated high school but worked at a cookware manufacturing plant before taking a job as a timekeeper for Bechtel Corp., according to Crouser's biography. He was drafted into the Army in May 1943 and soon was shipped to Germany to fight in World War II.
Moore managed to avoid the front lines during his first year in the Army. Blessed with a high IQ, he was tapped by the Army to train as an engineer as part of its Army Specialized Training Program.
That schooling abruptly stopped following the massive casualties of D-Day. The Army dissolved the specialized training program and reassigned its cadets to infantry and special-operations units. Moore, by then a sergeant, wound up in Germany.
During one firefight, Moore was shot by a German machine gunner. The bullet tore through his face, causing extensive damage and blood loss. Surgeons were able to repair much of the damage, but he still carries scars from the battle.
Back home in West Virginia, Moore finally was able to attend West Virginia University. He entered school as a junior thanks to the credits he earned with the Army Specialized Training Program. After completing his bachelor's degree, he stayed at WVU to earn a law degree.
Capito said her father maintained his love of learning throughout his years in public office.
"He always knew more than everybody in the room," she said.
When Capito began considering her 2014 run for U.S. Senate, she told her father before announcing it to the public.
"He looked at me, gave me the thumbs up, had a sparkle in his blue eyes and said, 'Let's go,' " Capito said.
Capito said her parents don't get around much anymore. Her mother has Alzheimer's disease while her father suffers from heart trouble and dementia. Their children visit as often as possible, working together to care for their parents. A nearby aunt and uncle also help, as do some paid caregivers.
"My dad was always a fighter, a very strong man, but he's met his match with his aging years," Capito said.
She said a different kind of strength has emerged in recent years.
Arch Moore rarely has talked about his faith in public. He never wore it on his sleeve or used God to gain political points.
But Capito said she has realized in recent years her father is a deeply devout man.
"It's much deeper and more intense than I had thought about. He really has relied a whole lot on a higher power," she said. "He believes in a bountiful and loving God, rich in forgiveness."
Wounded and bleeding in a foreign field, Moore once made God a promise: If he survived, he would dedicate the rest of his life to the service of others.
