Jonathan Harker is a fictional character and one of the main protagonists of Bram Stoker's 1897 Gothic horror novel Dracula. An English solicitor, his journey to Transylvania and encounter with the vampire Count Dracula and his Brides at Castle Dracula constitutes the dramatic opening scenes in the novel and most of the film adaptations. Stoker appropriated the surname from his friend Joseph Cunningham Harker (1855–1920), a set designer at the Lyceum Theatre in London and father of actor William Gordon Harker (1885–1967) as well as great-grandfather of actress Polly Adams, whose actress-daughters Susannah Harker and Caroline Harker adopted the Harker surname for their stage names.
