マーサ・グレアム
After Martha Graham's death in 1991, the center's leadership was debated. In her will, Martha Graham left Ron Protas as heir to her estate. Protas claimed ownership of the rights to Graham's name and choreographic oeuvre, and sued the Martha Graham Dance Company for trademark infringement. After years of legal battles, the Martha Graham Dance Company was ruled the owner of the Graham name and almost all of her repertoire. During the dispute, Protas was voted out of his position as artistic director of the company.
