Biography is a very definite region bounded on the north by history, on the south by fiction, on the east by obituary, and on the west by tedium.
Philip Guedalla (March 12, 1889 December 16, 1944) was a British barrister, and a popular historical and travel writer and biographer. He is remembered now mainly for a biography of the Duke of Wellington, and his wit and epigrams, one example being "Even reviewers read a Preface," another being "History repeats itself. Historians repeat each other." He also was the originator of a now-common theory on Henry James, writing that "The work of Henry James has always seemed divisible by a simple dynastic arrangement into three reigns: James I, James II, and the Old Pretender".
