Until he was old enough to buy and trade his own comic books, Gerald York thought his grandfather was just an ordinary man. Alvin C. York — Tennessee's most famed war hero and among the most recognized Americans from World War I — was "always fun."

Today, his name is known worldwide and is emblazoned across the state.

York's story starts and ends deep in the hills of northeast Tennessee, where his family farm still exists. It's not far from the two-lane highway that leads to the state park — both carry his name.

His war story will be told often as the centennial of the end of World War I comes later this year, and the anniversary of the battle that earned Sgt. Alvin York his fame.

His story, in a nutshell: In October 1918, York charged a hill alone, killed 25 deeply entrenched but fatigued German soldiers and captured 132 others.

Now, his grandson, Gerald York, 70, himself a veteran, will travel to northeastern France this October for the 100th anniversary of the battle of Chatel-Chéhéry, where his grandfather remains a celebrity.

Greatest battle was not in Europe

His family, though, remembers a much more ordinary man. His legacy, for those who knew him best, wasn't forged on the field of battle. Instead it is near his hometown in the walls of the only state-funded and managed public high school — it, too, carries York's name — in Fentress County, one of the most rural and poor counties in the state.

"He said the greatest battle he had was not in France, but was in Fentress County building a high school," Gerald York said. "People did not want a high school. They thought, why did their kids need education. They farmed. They needed them to farm."

Phil Brannon — superintendent of York Institute for three decades, the high school York established after his tour in Europe — said, "He realized what the mountain people were missing out on."

Alvin York established York Institute in Jamestown in 1926, and turned it over to the state in 1937. With barely a third-grade education himself, York was self-taught, and got the school running almost entirely on his own, Gerald York said.

"He bought the buses. He paid the drivers. He bought the gas," York said. "He paid the teachers, all with money he raised."

The school still operates today on a portion of the 400 acres that made up the campus. An elementary school also carrying his name stands on 40 acres.

York's great-niece, Janet Patton, also wonders what the state of education would have been without his success.

"I don't even know if we'd even had a high school if he hadn't done it," she said.

Discovering his grandfather's story

York rarely talked about his time in France during World War I.

Everyone else knew what he had done.

He received a Medal of Honor. There was a ticker-tape parade for him in New York. A movie starring Gary Cooper came out in 1941, which won two Oscars.

Just this year, the U.S. Treasury minted a new $1 coin featuring York's chiseled jawline and heavy mustache.

He didn't talk about his combat experience until his dying days, Gerald York said.

The story his grandfather was so known for wasn't something York learned until fifth grade, when his teacher asked him to read the encyclopedia passage on his grandfather to his classmates. "I guess that's the first time I realized that other than me and my family, that other folks knew my grandfather."
