Assistant Professor of History Daniel Tortora has written the 160-page Fort Halifax: Winslow’s Historic Outpost, due out April 1. A communal effort, the book emerged from the research efforts of Tortora and his two assistants, history majors David Thomas ’15 and Colin Hull ’15, with the help of many interviewees including Stan Mathieu ’57 and Jack Nivison (father of John Nivison ’82 and grandfather of Lauren Nivison ’11 and Jack Nivison ’14), whose photographs appear in the book.
