Gary Gerstle is the Paul Mellon Professor of American History at Sidney Sussex College, Cambridge University. He works on the twentieth-century United States, with a particular focus on how the United States periodically reconfigures its boundaries and national identity to open or close itself to immigrants and other minorities in its midst. He is the author of Liberty and Coercion: The Paradox of American Government from the Founding to the Present (2015), which won the OAH Ellis W. Hawley Prize, and American Crucible: Race and Nation in the Twentieth Century (2001), which won the Immigration and Ethnic History Society's Theodore Saloutos Book Award. He has been awarded many fellowships and has also been elected to the Society of American Historians.
