Professor Stephen Kantrowitz, a historian at the University of Wisconsin–Madison, has received the prestigious Andrew Carnegie Fellowship, awarded to only 24 scholars from a pool of 381 nominations. This $200,000 fellowship will support his research for his fourth book, titled 'Who is an American? The Contested History of U.S. Citizenship.' The book aims to explore the complexities of citizenship in the United States, particularly in the context of political polarization. Kantrowitz plans to create a companion website to facilitate discussions on these topics. UW–Madison Chancellor Jennifer Mnookin praised Kantrowitz's significant contributions to the fields of race, citizenship, and Native-settler relations in American history. With over 31 years at UW–Madison, Kantrowitz has authored several influential works, including analyses of Black citizenship and Native American history during the 19th century. The Carnegie Corporation of New York established this fellowship to support distinguished scholars in social sciences and humanities, emphasizing the importance of understanding and addressing political polarization in the U.S.
