Environmental, Borderlands, and Native American History

Karl Jacoby has devoted his career to understanding the ways in which the making of the United States intertwined with the unmaking of a variety of other societies—from Native American nations to the communities of northern Mexico—and the ecologies upon which they rested. His scholarship is distinguished by its close attention to questions of narrative and storytelling, in-depth micro-historical approach, and border-crossing nature. Professor Jacoby’s published work straddles multiple boundaries—not only the geographic divisions between East and West, and Mexico and the United States, but also the methodological divides between labor history and environmental history, genocide studies and Native American history, and borderlands history and African-American history.

Professor Jacoby received his A.B. in 1987 from Brown University and his Ph.D. in American history in 1997 from Yale University. After a year as a visiting assistant professor at Oberlin College, he returned to Brown as an assistant professor of history in 1999 and was named full professor in 2009. In the fall of 2012, he moved to Columbia University, where he currently serves as a professor in the Department of History and in the Center for the Study of Ethnicity and Race. He is the author of two books, Crimes Against Nature: Squatters, Poachers, Thieves, and the Hidden History of American Conservation(University of California Press, 2003) and Shadows at Dawn: A Borderlands Massacre and the Violence of History (Penguin Press, 2008), as well as numerous essays and reviews.
