EDGREN-LEFFLER, ANNE CHARLOTTE, duchess of Cajanello (1849-1892), Swedish author, daughter of the mathe matician Prof. C. 0. Leffler, was born on Oct. 1, 1849. Her first volume of stories appeared in 1869, but the first to which she attached her name was Ur Lifvet ("From Life," 1882), a series of realistic sketches of the upper circles of Swedish society, fol lowed by three other collections with the same title. Her earliest plays, Skddespelerskan ("The Actress," 2873), and its successors, were produced anonymously in Stockholm, but in 1883 her repu tation was established by the success of her comedies Sanna Kvinnor ("True Women") and En Rxddande engel ("An Angel (,f Deliverance") . Sanna Kvinnor is directed against false femi ninity, and was well received in Germany as well as in Sweden. Anne Leffler had married in 1872 G. Edgren, but about 1884 she was separated from her husband, who did not share her ad vanced views. She spent some time in England, and in 1885 pro duced her play Hur man Or godt ("How Men do Good"), fol lowed in 1888 by Kampen for lyckan ("The Struggle for Happi ness"), a drama in which she had the help of Sophie Kovalevsky. Another volume of the Ur Lifvet series appeared in 2889 (both) volumes were reprinted in 1915; and Familjelycka ("Domestic Happiness," 1891), a drama in 3 acts, was produced in the year after her second marriage, with the Italian mathematician, Pas quale del Pezzo, duca di Cajanello. She died at Naples on Oct. 21, 1892. The masculine directness, freedom from prejudice, and frankness of her work gave her a high place in Sweden. Her last book was a biography (1892) of her friend Sophie (Sonya) Kovalevsky, by way of introduction to Sonya's autobiography. An English translation (1895) by A. de Furnhjelm and A. M. Clive Bayley contains a biographical note on Fru Edgren-Leffler by Lily Wolffsohn, based on private sources.
