John Barry Humphries is an Australian comedian, actor, satirist, artist, and author. He is best known for writing and playing his on-stage and television alter egos Dame Edna Everage and Sir Les Patterson. He is also a film producer and script writer, a star of London's West End musical theatre, an award-winning writer, and an accomplished landscape painter. For his delivery of dadaist and absurdist humour to millions, biographer Anne Pender described Humphries in 2010 as not only "the most significant theatrical figure of our time … [but] the most significant comedian to emerge since Charlie Chaplin". Humphries' characters have brought him international renown, and he also appeared in numerous stage productions, films, and television shows. Originally conceived as a dowdy Moonee Ponds housewife who caricatured Australian suburban complacency and insularity, Dame Edna Everage has evolved over four decades to become a satire of stardom – a gaudily dressed, acid-tongued, egomaniacal, internationally fêted Housewife "Gigastar". Humphries' other satirical characters include the "priapic and inebriated cultural attaché" Sir Les Patterson, who has "continued to bring worldwide discredit upon Australian arts and culture, while contributing as much to the Australian vernacular as he has borrowed from it"; gentle, grandfatherly "returned gentleman" Sandy Stone; iconoclastic 1960s underground film-maker Martin Agrippa; Paddington socialist academic Neil Singleton; sleazy trade union official Lance Boyle; high-pressure art salesman Morrie O'Connor; failed tycoon Owen Steele; and archetypal Australian bloke Barry McKenzie.
