C. R. M. F. Cruttwell

Charles Robert Mowbray Fraser Cruttwell was a British historian and academic who served as dean and later principal of Hertford College, Oxford. His field of expertise was modern European history, his most notable work being A History of the Great War, 1914–18. He is mainly remembered, however, for the vendetta pursued against him by the novelist Evelyn Waugh, in which Waugh showed his distaste for his former tutor by repeatedly using the name "Cruttwell" in his early novels and stories to depict a sequence of unsavoury or ridiculous characters. The prolonged minor humiliation thus inflicted may have contributed to Cruttwell's eventual mental breakdown.
