Swedish company which dates back to 1920 when the local Stora Teater became a full-time opera house with a resident ballet company. As in most European opera houses, the ballet was usually to be found in opera productions and evenings devoted to ballet were initially rare. However Ivo Cramér, Cullberg, and Massine worked with the company in the 1950s, and Cullberg and Lifar staged several productions there during the 1960s. In 1967 Conny Borg's appointment as ballet director created a new era for the company, as Borg attempted to build up a repertory of new and contemporary ballets with guest choreographers such as Cullberg, Cramér, Gore, Lander, and Petit. In 1970 Borg was succeeded by E. M. von Rosen, who added a more classical focus to the repertory with stagings of Napoli, La Sylphide, Swan Lake, and Romeo and Juliet. But Ulf Gadd (artistic director 1976–88) and Flemming Flindt also contributed new works as did US choreographer Robert North, who was artistic director from 1991 to 1996, and created The Snowman (mus. Howard Blake) for the 1993–4 season. In 1996 Ulf Gadd returned as artistic director; succeeded by Anders Hellström in 1999 and by Johannes Öhman in 2007.
