Russell Frank Weigley (WY-glee) (July 2, 1930 – March 3, 2004) was the Distinguished University Professor of History at Temple University in Philadelphia, Pennsylvania, and a noted military historian. His research and teaching interests centered on American and world military history, World War II, and the American Civil War. One of Weigley's most widely received contributions to research is his hypothesis of a specifically American Way of War, i.e. an approach to strategy and military operations, that, while not predetermined, is distinct to the United States because of cultural and historical constraints.
