A brass bust of Swedish male playwright and novelist August Strindberg keeps watch permanently outside Stockholm's Royal Dramatic Theatre.
But according to Andreasson, in the 1880s he wasn't even the theatre's most celebrated playwright: Alfhild Agrelle was.
"She was bigger than Strindberg and he hated her," Andreasson tells Radio Sweden. "He was really obsessed with Alfhild Agrelle because she was more successful than him."
When Agrelle's plays were played in London, she received rave reviews, Andreasson says. The English theatre critics, perhaps confusing her name with the English male name Alfred, believed she was a man.
"They said Henrik Ibsen and Alfhild Agrelle are the greatest playwrights of he Nordic countries."
Ensam, or Alone, tells the story of a mother and her illegitimate daughter living on the Stockholm island of Kungsholmen, then called 'Svältholmen', or 'hunger island', because its poverty and overpopulation.
The play's themes are shame, female sexuality and resilience in the face of social injustice.
"They are totally a social disgrace," Andreasson explains. "But this play is interesting because the woman, the mother, she refuses to be ashamed. You can feel it pounding, this feeling of fighting for your right as a human being."
Andreasson was at Stockholm's Royal Dramatic Theatre on Thursday for the announcement of its autumn programme.
Ensam has its opening night on September 1.
