Philip Guedalla was an English barrister, and a popular historical and travel writer and biographer. His wit and epigrams are well-known, 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".
