As an artist, Martha Graham conceived each new work in its entirety – dance, costumes, and music. During her 70 years of creating dances, Martha Graham collaborated with such artists as sculptor Isamu Noguchi; actor and director John Houseman; fashion designers Halston, Donna Karan and Calvin Klein; and renowned composers including Aaron Copland, Louis Horst (her mentor), Samuel Barber, William Schuman, Carlos Surinach, Norman Dello Joio, and Gian Carlo Menotti. Her company was the training ground for many future modern choreographers, including Merce Cunningham, Paul Taylor, and Twyla Tharp. She created roles for classical ballet stars such as Margot Fonteyn, Rudolf Nureyev, and Mikhail Baryshnikov, welcoming them as guests into her company. In charge of movement and dance at The Neighborhood Playhouse, she taught actors including Bette Davis, Kirk Douglas, Madonna, Liza Minnelli, Gregory Peck, Tony Randall, Anne Jackson, and Joanne Woodward how to use the body as an expressive instrument.
