One of the pioneers of American modern dance, Martha Graham was a performer, teacher, choreographer and company director nearly until her death. Her many works were created in collaboration with some of the most celebrated artistic talents of the century, including Aaron Copland and Isamu Noguchi. Many of her students, such as Erick Hawkins, Paul Taylor and Merce Cunningham, went on to fame in their own right. Some of her most popular works include "Appalachian Spring" (1946) and "Clytemnestra" (1958).
