husband and wife who devised the Benesh system of dance notation. Rudolf (b London, 16 Jan. 1916; d London, 3 May 1975), an engineer, and Joan (née Rothwell; b Liverpool, 24 Mar. 1920), a dancer, developed their system in 1955 and began teaching it in 1956 at the Royal Academy of Dancing. In 1960 the Royal Ballet became the first company to hire a professional choreologist. In 1962 Joan and Rudolf Benesh founded the Institute of Choreology, since renamed the Benesh Institute (and incorporated into the Royal Academy of Dancing). The Benesh Institute is responsible for training choreologists and for preserving notated scores. Benesh notators now work with virtually every major ballet company in the Western world. Most new ballets are notated in the Benesh system, while Labanotation continues to be favoured by those working in non-classical dance. Benesh Movement Notation uses a five-line stave, similar to music, with symbols that represent the various positions and movements of a body.
