Who invented freestyle skiing mogul?

Freestyle skiing mogul was popularized in the late 1970s and early 1980s, but it doesn't have a single inventor. It evolved from various skiing disciplines, with significant contributions from athletes like Canadian skier John D. "Duke" Gibbons, who is often credited with helping to formalize the sport. The first official mogul competition took place in 1980, further establishing the sport's recognition and structure.
