The AHA mourns the passing of Judith Allen, Distinguished Professor and Walter Professor of History at Indiana University (IU), Bloomington. Educated at the University of Sydney, Judith completed her PhD at Macquarie University in 1985, before taking up a position as the first chair of women’s studies in Australia. In 1993, she relocated to IU where she was both Professor of History and founding director of the Department of Gender Studies. Judith’s landmark contributions to the field of gender history include Sex and Secrets: Crimes Involving Australian Women since 1880 (1990), Rose Scott: Vision and Revision in Feminism, 1880-1925 (1994) and The Feminism of Charlotte Perkins Gilman: Sexualities, Histories, Progressivism (2009). A valued and highly esteemed colleague, mentor and teacher, she served the profession in several capacities including as a long-term Associate Editor of the Journal of American History, as a senior research fellow at the Kinsey Institute for Research in Sex, Gender, and Reproduction since 2014, and as a valued member of the Editorial Board of our own History Australia journal. The AHA extends its deepest sympathies to her colleagues, friends and family, particularly her husband, Peter Bailey.
