Best Answer - Chosen by Asker: changed the classical arm positions for her?

That was Maria Taglioni, the first ballerina to dance on pointe. Her father, the Dance Director for the Paris Opera, choreographed the arm positions where the hands are crossed at the wrists, a symbol of Romantic Ballets, simply to make her arms look shorter. And the look stuck, and everyone began to choreograph that way.

I think you are asking about Marie Taglioni and her father Phillippe Taglioni. I don't believe that he changed the classical arm positions for her...those are a constant. However, he choreographed works for her with arms bent and wrists cross in front of her chest "a la Chopinia" or "La Sylphide" that hid the length of her arms.
