From 1900 through 1930, American dancers, Isadora Duncan and Ruth St. Denis, and German dancer, Mary Wigman, had started to develop modern dance. This new development was a combination of the expressive gestures initiated by French actor – Francois Delsarte; and the musical rhythms created by Swiss music educator – Emile Jacques-Dalcroze.
In order to show freer forms of dance, early modern dance adopted exotic and ethnic sources for inspiration – this happened at the same period of time when ballet choreographers are searching or the same ideas. Isadora Duncan used Greek sculpture as a movement source; she danced with bare feet using music from romantic composers.
Ruth St. Denis on the other hand, adapted Asian dance styles. When she and her husband, Ted Shawn, opened a dance company, Denishawn, in 1915, she taught the students her ethnic styles of dancing. Mary Wigman also adapted dances from the Orient and Africa in which she used masks as part of the presentation.
After 1930, newer modern dancers popped up in New York, including the two most important figures of the U.S. modern dance history - Martha Graham and Doris Humphrey.

Graham’s theory on contraction and release movements has become the focus of the modern dance in the U.S. She was also the first choreographer to collaborate with other modern dancers as can be seen in “Appalachian Spring”.
Both Graham and Humphrey had performed with the German-American dance, Hanva Holm who was trained by Mary Wigman’s school. In the late 1940s, Holm was one of the first to bring a new style of modern dance to the Broadway shows.
