Replying to History of Freestyle skiing

I have an English assignment, I need some people to tell me some skiers that helped evolve freestyle skiing and how
(Candide, JP, etc.....)

What used to influence free skiing? Do the influences continue to change with different styles(baggy, bunch, etc)



If some of you could answer these so I can quote you and pass english it would mean a lot
+k if u still care about that
