She was the daughter of the school principal John Olof Leffler and Gustava Wilhelmina Mittag. Her brother was noted mathematician
Gösta Mittag-Leffler. Leffler was initially educated privately and then studied at the
Wallinska skolan from the age of thirteen, at that time perhaps the most progressive school open to females in Stockholm. Her first volume of stories appeared in 1869, but the first to which she attached her name was ("From Life," 1882), a series of realistic sketches of the upper circles of Swedish society, followed by three other collections with the same title. Her earliest plays, ("The Actress," 1873), and its successors, were produced anonymously in
Stockholm, but in 1883 her reputation was established by the success of ("True Women") and ("An Angel of Deliverance"). is directed against false femininity, and was well received in
Germany as well as in Sweden. Leffler had married G. Edgren in 1872, but about 1884 she was separated from her husband, who did not share her advanced views. She spent some time in England, and in 1885 produced her ("How one does good"), followed in 1888 by ("The Struggle for Happiness"), with which she was helped by
Sofia Kovalevskaya. Another volume of the series appeared in 1889, and ("Domestic Happiness," 1891) was produced in the year after her second marriage (to the Italian mathematician,
Pasquale del Pezzo, duke of Cajanello). Her dramatic method forms a connecting link between
Ibsen and
Strindberg, and its masculine directness, freedom from prejudice and frankness won her work great esteem in Sweden. Her last book was a biography (1892) of her friend
Sofia Kovalevskaya, by way of introduction to Sonya's autobiography. An English translation (1895) by
Annie de Furuhjelm and
A. M. Clive Bayley contains a biographical note on Fräu Edgren-Leffler by
Lily Wolffsohn, based on private sources. ==Bibliography==
