The Norwegian Sondre Norheim is often called the "father of modern skiing". In the 19th century, Norheim invented bindings that enabled the skier to do turns while skiing down hills. This form of skiing was called Slalom by Norheim and his contemporaries.
Many believe that freestyle snowboarding owes much of its form and content to skateboarding. Since a snowboard is attached securely to your feet, you are unable to perform many of the skateboard tricks, like a kickflip.
