Ann Blair is Henry Charles Lea Professor of History at Harvard University, where she teaches in book history and the intellectual and cultural history of early modern Europe (with a focus on France and Northern Europe in the sixteenth and seventeenth centuries). She is the author of The Theater of Nature: Jean Bodin and Renaissance Science (Princeton University Press, 1997), which was designed as a “total history” of a book of encyclopedic natural philosophy of 1596. Most recently she studied reference books in manuscript and print c.1500–1650 in Too Much To Know: Managing Scholarly Information before the Modern Age (Yale University Press, 2010). She is especially interested in practices of learning and scholarship in early modern Europe, including note-taking and composing. She is currently working on a book version of the Rosenbach Lectures she delivered at the University of Pennsylvania in 2014 on amanuenses and authorship in early modern Europe.
