Terence Zuber is an American military historian specializing in the First World War. He received his doctorate from the University of Würzburg in 2001 after serving for twenty years as an infantry officer in the United States Army. He has advanced the controversial thesis that the Schlieffen Plan as generally understood was a post-World War I fabrication.^[1][2]

He first described his views about the Schlieffen Plan in a 1999 article in War in History, and further developed them in his 2002 book Inventing the Schlieffen Plan. Some scholars, such as Hew Strachan, have largely accepted his ideas, while others including Terence M. Holmes and Holger Herwig have dismissed them.^[1]

In a review of Zuber's 2002 book for H-Net, Kelly McFall wrote: "Zuber's argument persuasively demolishes the commonly accepted version of the Schlieffen Plan. But his claim that the Schlieffen Plan itself never existed is more speculative and rests on a reading of evidence that is plausible but not conclusive. Military historians interested in the outbreak of the First World War will need to read this book and decide for themselves. Others will want to follow the debate closely, but may prefer to wait for a consensus to emerge."^[1]

Perhaps most importantly, in 2006, Germany’s Military History Research Office (MGFA) published Der Schlieffenplan: Analysen und Dokumente, edited by Michael Epkenhans, Hans Ehlert and Gerhard P. Groß (The Schlieffen Plan: Analyzes and documents. Age of World Wars, Volume II ). This volume contains a copy of Schlieffen's 1905 Memorandum misfiled in the German Military Archives at Freiburg and German deployment plans from the year 1893/94 to 1914/15, most of which had been lost otherwise. These documents, not yet available in English translation, are said to strongly support the traditional ideas of a "Schlieffen Plan" that Zuber disputed.^[3][4]
