Doris Humphrey came out of the Denishawn School and is known as one of the "pioneers" of modern dance. Her and Charles Weidman developed "fall and recovery" technique. This dance technique lmakes those studying it to be proficient in balancing and ceding to the pull of gravity. The Humphrey-Weidman Dance Company was started and was interested in group dynamics and choreographed many dances that highlighted the group instead of soloists. She equally worked with music visualization.
As it is very different to what most play writers (not sure if correct word) would write about. it showed and developed ideas that people weren't use to seeing on stage making it very different.
