Danish architect Sidse Werner (1931–1989) studied at the Kunstakademiet in Copenhagen and subsequently worked as an assistant in Nanna Ditzel's drawing office. In 1970 she set up her own studio, from where she designed furniture, textiles, glass and lighting. For her Formland lights project for Fog & Mørup she teamed up with Leif Ålring, and the pair worked closely with F&M's head of design Jo Hammerborg both in the lights' design and in the skydiving-themed marketing of the Formland series.
