Deb Henningsen's father taught her to water ski on old Lake Shady in Oronoco, Minn., in the 1960s.
"The lake was calm as glass, and he was so patient," said Henningsen, 71, from her family's farm near Grundy Center, Iowa. "He wanted me to start from the dock and I couldn't do it to save my soul. But once I got in the water and leaned back, I was up."

It was like taking flying lessons from Orville Wright or serving as printing apprentice to Johannes Gutenberg. Deb's dad, Ralph Samuelson, invented water skiing 100 summers ago in Lake City, Minn.
After days of failed experiments with barrel staves and snow skis, Samuelson rose through the splashing water of Lake Pepin at 4:11 p.m., July 2, 1922, on 15-pound pine boards nearly 9 feet long. He was pulled behind a clamming boat powered with a truck engine and piloted by his brother Ben.
The historic feat by Samuelson, who turned 19 the next day, was largely forgotten for more than 40 years before the American Water Ski Association recognized him in 1966 as "the first water skier of record." Five years later, a historical marker went up along Lake Pepin, proclaiming it the "Birthplace of Waterskiing."
In the 1920s, Samuelson put on ski shows at water carnivals from Minnesota to Florida, at one point slathering lard on floating jumps and skiing at 80 mph behind a Curtiss seaplane. He never wore a life jacket.
But he didn't patent his invention or cash in on his breakthrough. In fact, he endured several pitfalls: a failed marriage, two brothers dying as children and bankruptcy after disease killed the flock on his Mazeppa turkey farm in 1952. When he fractured his back while building a boathouse in Florida, it spelled the end to his water skiing antics.
Samuelson didn't mind the initial obscurity that blanketed his innovation. People in France and New York initially boasted about being first on water skis, but those claims were debunked in the 1960s by newspaper clippings and eyewitness accounts.
