Hannah Marcus's research focuses on the scientific culture of early modern Europe between 1450 and 1700. Marcus earned her BA at the University of Pennsylvania and her PhD at Stanford University in 2016. Before coming to Harvard she worked as a postdoctoral researcher on the Galileo Correspondence Project, which she directs with Paula Findlen.


Marcus has two book projects underway. The first, The Utility of Prohibited Knowledge: Medicine, Readers, and Censors in Early Modern Italy, 1500-1664, explores the censorship of medical books from their proliferation in print through the prohibitions placed on many of these texts during the Counter-Reformation. This account explains how and why the books prohibited in Italy ended up back on the shelves of private and public Italian libraries in the seventeenth century. The second book, co-authored with Paula Findlen, is a study of Galileo’s correspondence called Galileo’s Letters: Experiments in Friendship. This book grows out of their collaboration on The Galileo Correspondence Project, a digital humanities project begun at Stanford.

Marcus teaches courses on the changes in scientific ideas and practice between 1500 and 1700 (often known as the Scientific Revolution), the early history of medicine and the body, art and technology in the Renaissance, and the relationship between faith and science in the early modern period.
