His family eventually moved to the United States, where he settled and began to build a life. Before the world knew him as the father of an Olympic hero, he was a young man with a future forged by the challenges of his time. It was this humble, hardworking background that created the man who would face one of history’s greatest conflicts with unshakeable courage.

The defining chapter of William Hugh Jenner’s young life was his service in the U.S. Army during World War II.

As part of the Allied invasion, he stormed the beaches of France in an operation that changed the course of the war.
Facing unimaginable danger, William fought bravely and was wounded in action, an act of sacrifice that earned him the prestigious Purple Heart.

This career choice spoke volumes about his personality. It was honest, hard work that required him to be both tough and careful. His children, including Caitlyn, remember him as a man who was not afraid to get his hands dirty.
