Professor of History and American Culture (Latina/o Studies) at the University of Michigan. He is author of A Tale of Two Cities: Santo Domingo and New York after 1950 (Princeton 2008). His recent book, Racial Migrations: New York City and the Revolutionary Politics of the Spanish Caribbean, 1850-1910 (Princeton, 2019), explores the lives and intellectual productions of a group of radicals and revolutionaries from Puerto Rico and Cuba who, like the main characters in the Broadway play Hamilton, were immigrants who negotiated paths of social mobility “up from the bottom,” while conspiring to overthrow a colonial monarchy, end slavery, and establish a liberal republic. But unlike Hamilton, casting these figures as black or Latina/o requires no act of counterfactual imagination. They were, for the most part, both black and Latina/o. In Racial Migrations, Hoffnung-Garskof tries to understand what kinds of politics those overlapping racial and national identities allowed, shedding new light on Caribbean revolutionary movements that took shape within and across New York’s idiosyncratic color lines. Professor Hoffnung-Garskof is also the director of the Immigrant Justice Lab at the University of Michigan.
