Bruce Mazlish (September 15, 1923 – November 27, 2016) was an American historian who was a professor in the Department of History at the Massachusetts Institute of Technology. His work focuses on historiography and philosophy of history, history of science and technology, artificial intelligence, history of the social sciences, the two cultures and bridging the humanities and sciences (natural and social), revolution, psychohistory, history of globalization and the history of global citizenship. He has worked to build the latter two into a public intellectual movement, through initiatives such as the New Global History conferences.
