High Quality Content by WIKIPEDIA articles! Walter Charles Langer (February 5, 1899 – July 4, 1981) was a Cambridge, Massachusetts psychoanalyst best known for his role in preparing a World War II psychological analysis of Adolf Hitler in 1943 for the Office of Strategic Services, that predicted his suicide as the "most plausible outcome" among several possibilities identified. Well before the assassination attempt in the summer of 1944, Langer`s report also identified the possibility of a military coup against Hitler. The report is available online and, along with collateral material including a foreword, introduction and afterword, was published in 1972 by Basic Books as The Mind of Adolf Hitler.
