From 1956 to 1978, Gertrud Fridh was part of the ensemble at Sweden's national stage, the Royal Dramatic Theatre in Stockholm. There she performed a number of celebrated parts, from Titania in A Midsummer Night's Dream (1956) to Phaedra in Euripides' Hippolytus (1965) and The Mummy in Strindberg's The Ghost Sonata (1973). One of her most praised parts was her Hedda Gabler, in the legendary 1964 Dramaten production of the Ibsen play, directed by Bergman. The successful production gave 89 performances, and she later guest performed in Helsinki, Berlin and London. Despite the fact that many Swedish actresses have taken on the role of Hedda Gabler over the years, in Sweden, Gertrud Fridh is still regarded as the definitive Hedda of all time.
