Ellen Hartigan-O’Connor is associate professor of history at the University of California at Davis, where she teaches courses on gender, American social and cultural history, and the histories of colonialism and capitalism. She is the author of THE TIES THAT BUY: WOMEN AND COMMERCE IN REVOLUTIONARY AMERICA (University of Pennsylvania Press, 2009), as well as articles and book chapters on gender and economy in the eighteenth and nineteenth centuries. With support from the National Endowment for the Humanities, she is currently completing a project on auctions and market culture in early America, tracing the economic and cultural power of a widespread but little-studied institution.

She is co-editor of the OXFORD HANDBOOK OF AMERICAN WOMEN’S AND GENDER HISTORY (Oxford University Press, forthcoming), and a board member of Women and Social Movements. A Founding and Standing Editor of Oxford Bibliographies Online: Atlantic History, Dr. Hartigan-O’Connor is also a speaker with the Organization of American Historians’ Distinguished Lectureship Program.
