After a two-month search, James Marcus has been named the newest editor of Harper’s.

Marcus, who becomes Harper’s 16th editor, joined the 165-year-old publication in 2010, first serving as deputy editor before being appointed executive editor in 2013. Marcus was previously editor-at-large at the Columbia Journalism Review, and has contributed articles to the New York Times, the Los Angeles Times, the Atlantic, Salon, Lingua Franca, the Village Voice, The Philadelphia Inquirer, the Nation and Story Quarterly.

Marcus succeeds Christopher Cox, a former Paris Review senior editor who joined Harper’s in 2010 and was promoted to deputy editor in 2013. Cox served as Harper’s editor for only three months; after being appointed to that role in October, he was unexpectedly fired in late January by publisher John R. MacArthur. A February 2 The New York Times report on the incident posited that Cox had been terminated over disagreements regarding the magazine's editorial direction.

Harper's in a statement said Marcus would assume the new position after completion of his latest book, which is slated for publication in 2017 from Metropolitan Books.

Ellen Rosenbush, who Cox initially succeeded as editor in October, had been serving as interim editor while Harper’s, the second-oldest continuously published monthly magazine in the country, searched for Cox's permanent successor. Rosenbush, who has been with Harper's since 1989 and was the first female at the magazine to fill the editor position, continued contributing to Harper's in the role of editor-at-large. She will resume that role in June.
