マーサ・グレアム
Martha Graham founded a school, the Martha Graham Center of Contemporary Dance, which she sold in 1956. After Graham's death, Ron Protas, her sole heir, sued the school for the rights to use Graham's trademarked name and choreography. A federal court awarded the school the rights to the names "Martha Graham" and "Graham technique" in 2001, and the rights to Graham's choreography in 2002.
