William John Warner (1866–1936), known professionally as Cheiro, was the most commercially successful palmist of the late Victorian and Edwardian eras. His client list included statesmen, royalty, and international celebrities. However, popular accounts frequently blur the line between contemporary dated records and stories published decades later in his 1927 autobiography, Confessions: Memoirs of a Modern Seer.
When evaluated under rigorous historical standards, Cheiro's record splits into three distinct categories: genuine dated character analysis (such as Mark Twain's hand reading), broad pre-event published timing forecasts (such as King Edward VII's death in his 69th year), and unverified retrospective claims published long after the fact (such as the Titanic legend). Furthermore, his 1931 book World Predictions contains explicit, verifiable failures that popular biographies systematically omit.
