She was born Joan Dorothy Rothwell in the
Wavertree district of Liverpool in 1920. She studied dance for three years in Liverpool at the Studio School of Dance and Drama and then studied with
Lydia Sokolova. She won the ballet prize of the All England Dance Competition in 1937 and the Parker Trophy for Dance in 1938. She then worked as a dancer and choreographer in commercial theatre where, in 1947, she met the accountant, artist and musician, Rudolf Benesh, who noticed that she was having trouble: "During a break while I was painting Joan's portrait, I mused at her struggle to get down on paper her choreographic ideas for a ballet". He began
a notation to help her record her dances and they developed the system together. The couple married on 12 March 1949 and she then joined the
Sadler's Wells Ballet Company. ==Benesh Movement Notation==
