Anne Teresa, Baroness De Keersmaeker (, born 1960 in Mechelen, Belgium, grew up in Wemmel) is a contemporary dance choreographer. The dance company constructed around her, , was in residence at La Monnaie in Brussels from 1992 to 2007. Biography De Keersmaeker did not study dance until her last year of high school, instead studying music, specifically the flute. She studied from 1978 to 1980 at Mudra in Brussels, a school with links to La Monnaie and to Maurice Béjart's Ballet of the 20th Century. She has said that the percussionist and her music teacher at MUDRA, , was a major influence on her. In 1981, she attended the Tisch School of the Arts at New York University. While at the Tisch she presented her first production, Asch (1980), in Brussels. In 1982 upon her return from the U.S.A. she created , four movements to the music of Steve Reich. It was this production that brought her "a breakthrough on the international dance scene, performing, among other places, at the Avignon Festival". The success of Fase contributed largely to the foundation of the Rosas in 1983. Rosas danst Rosas - Anne Teresa De Keersmaeker's first choreography for the young company to new compositions of Thierry De Mey and Peter Vermeersch - brought Rosas the international breakthrough as a company. During the eighties, Rosas was supported by Kaaitheater of Brussels (director Hugo De Greef). Within the framework of Kaaitheater, her oeuvre took shape. Performances such as Elena's Aria (1984), Bartók/Aantekeningen (1986), a staging of Heiner Müller's triptych Verkommenes Ufer/Medeamaterial Landschaft mit Argonauten (1987), Mikrokosmos-Monument Selbstporträt mit Reich und Riley (und Chopin ist auch dabei)/In zart fliessender Bewegung - Quatuor Nr.4, (1987), Ottone, Ottone (1988), Stella (1990) and Achterland (1990) were produced in collaboration with Kaaitheater. In 1992, La Monnaie's general director Bernard Foccroulle invited Rosas to become the resident company of Brussels' Royal Opera De Munt/La Monnaie. At the start of the residency, Anne Teresa De Keersmaeker set herself three objectives: to intensify the relation between dance and music, to build a repertory, and to launch a dance school (after the disappearance of MUDRA from Brussels in 1988). That year, Rosas created ERTS and released Rosa - a film of a choreography by Anne Teresa De Keersmaeker to Bartók music directed by Peter Greenaway. Later that year, Rosas created Mozart Concert Arias, un moto di gioia for the Avignon Festival. A
