Edna Mahan served as Superintendent of the New Jersey Reformatory for Women for forty years (1928-1968). She rescued the reformatory tradition of separate, rehabilitative institutions for female offenders as it was beginning to flag and sustaining it into the 1960s. She served as a link with the original philosophy of female prisons and is a model for those who, today, seek to rehabilitate, not punish. She was one of the most powerful and successful of twentieth century women's prison superintendents.
The article is based on my biography of Edna Mahan, Excellent Effect: The Edna Mahan Story, published in 1994 by the American Correctional Association. It draws on institutional board minutes, reports, and studies; Mahan's diaries, correspondence, and professional papers; American Correctional Association publications; interviews: and my personal acquaintance with Mahan.
