In 1922, an enterprising 18-year-old water-sports enthusiast, Ralph Samuelson, came up with the idea of waterskiing on Lake Pepin in Minnesota. After trying wooden barrel staves and actual snow skis for skis, he ended up with his own design and bindings made of leather. Samuelson is also credited with the first ski jump using a greased ramp. He spent the next 15 years performing shows and promoting his sport, at one point even being pulled by a World War II flying boat to reach a speed of 80 miles per hour, making him the first speed skier. Unfortunately, he never patented his invention.
