Maurice Isserman writes pathbreaking books on the American left - and on mountaineering. In the latter category are Fallen Giants: A History of Himalayan Mountaineering from the Age of Empire to the Age of Extremes (2008, with Stewart Weaver); and Continental Divide: A History of American Mountaineering (2016). In the former can be found Which Side Were You On? The American Communist Party During the Second World War (1982); If I Had a Hammer: The Death of the Old Left and the Birth of the New Left (1987); America Divided: The Civil War of the 1960s (2000, with Michael Kazin); and The Other American: The Life of Michael Harrington (2000).
