1929

The figure of the zombie has appeared several times in fantasy themed fiction and entertainment, as early as the 1929 novel The Magic Island by William Seabrook. Island is the sensationalized account of a narrator in Haiti who encounters voodoo cults and their resurrected thralls. Time claimed that the book "introduced 'zombi' into U.S. speech".
