Mary Gunvor Irene Andersson ((1929-09-29)29 September 1929 – (2020-01-18)18 January 2020), was a Swedish author and playwright.

[1] Born as one of seven children to a working-class family in Tunaberg in 1929, Andersson spent most of her childhood in an orphanage in the Sorgenfri (literally "care free") district of Malmö.

[1] She suffered from anaemia at a young age, and started working at the age of 13,[2] with her experiences of working in a mustard factory later forming the basis of her 1991 book Dåliga mänskor (Bad People), which was later performed as a play at the Malmö Music Theatre in 1999.

Her first radio play, the 1979 Tjänsteflickan (The Maid), was an autobiographical story of her life until then, and was also published as a novel in 1984.

The book Andersson also wrote non-fiction, including in 1980 Asbestarbetarna berättar (The Asbestos Workers Tell) about the working conditions in an asbestos cement factory, and Maria och Almathea (Maria and Almathea) in 1988 about the 1908 harbour workers' strike in Malmö.
