Louis Silvie Zamperini (born January 26, 1917) is a World War II prisoner of war survivor, inspirational speaker, and former American Olympic distance runner.

Louis Zamperini was born in Olean, New York, to Anthony and Louise Zamperini. He had an older brother named Pete, and two younger sisters, Virginia and Sylvia. The Zamperini family moved to Torrance, California in the 1920s, where Louis attended Torrance High School. The son of Italian immigrants, Louis spoke no English when his family moved to California. This made him a target for bullies, so his father taught him how to box in self-defense. Soon he was "beating the tar out of every one of them... but I was so good at it that I started relishing the idea of getting even. I was sort of addicted to it."

"Before long he was picking fights just to see if anyone could keep up with him. From juvenile thug, he progressed to 'teenage hobo.' Hopping a train to Mexico, he courted danger for the thrill of it. 'I caught a wild cow in a ravine and tore my kneecap till it was just hanging off,' he recalled. 'I snapped my big toe jumping out of some giant bamboo; they just sewed it back on. I’ve got so many scars, they’re criss-crossing each other!'"

Laura Hillenbrand (born May 15, 1967) is an American author of books and magazine articles.

Born in Fairfax, Virginia, Hillenbrand spent much of her childhood riding bareback "screaming over the hills" of her father's Sharpsburg, Maryland, farm. A favorite of hers was Come On Seabiscuit, a 1963 kiddie book. "I read it to death, my little paperback copy," she says. She studied at Kenyon College in Gambier, Ohio, but was forced to leave before graduation when she contracted Chronic Fatigue Syndrome, which she has struggled with ever since. She now lives in Washington, D.C, and rarely leaves her house because of the condition. Hillenbrand married Borden Flanagan, a professor of Government at American University and her college sweetheart, in 2008.

Hillenbrand's first book was the acclaimed Seabiscuit: An American Legend (2001), a non-fiction account of the career of the great racehorse Seabiscuit, for which she won the William Hill Sports Book of the Year in 2001. She says she was compelled to tell the story because she "found fascinating people living a story that was improbable, breathtaking and ultimately more satisfying than any story [she'd] ever come across." She first told the story through an essay she sold to American Heritage magazine, and the feedback was positive, so she decided to proceed with a full non-fiction book. Upon the book's release, she received rave reviews for her storytelling and research. It was made into the Academy Award nominated film Seabiscuit (2003).
