John Mosier is an American academic known for his work in English, film, and history.
Mosier received his Ph.D. in 1968, from Tulane University. He completed his dissertation on the links between poetry and historiography.
Mosier is probably best known for his revisionist military history books. These books The Myth of the Great War: A New Military History of World War I and The Blitzkrieg Myth: How Hitler and the Allies Misread the Strategic Realities of World War II. In each of these books, Mosier challenges the current views held in regard to these conflicts. In The Myth of the Great War, Mosier argues that Germany was winning World War I, and only the arrival of the United States spared the Allies from military defeat and a negotiated peace with the Germans. In The Blitzkrieg Myth, Mosier argues that the supposedly revolutionary concept of blitzkrieg has been overrated and that most of the victories on both sides were the result of conventional military tactics. Both of these books and their thesis remain controversial. He also recently published a military biography of Ulysses S. Grant. The book was revisionist in method; however, his thesis focused on the more traditional view that Grant was a genius. This deviates from Mosier's previous revisionist tendencies.
Mosier is currently a professor of English at Loyola University New Orleans. In addition to his books on military history, Mosier serves on Cannes Film Festival committees, and works as writer and editor for publications such as the journal of the Organization of American States
