Chapter one provides a case study of Henry Neville Hutchinson, a frequently overlooked figure who was not only the most important early populariser of American dinosaurs but also a proponent of using imaginative literature to widen the mass public’s access to science. An unbeneficed British clergyman without a formal scientific position, Hutchinson aired his views both in popular journalism and in books on palaeontology like Extinct Monsters (1892). His writings often contradicted the views of palaeontological authorities. This chapter argues that palaeontologists who read Hutchinson’s democratising works with concern responded by fashioning clearer distinctions between true science and work that was popularisation or romance. In 1894 British palaeontologist Harry Seeley described Hutchinson’s writing as ‘literature rather than science’. As Fallon demonstrates, Seeley’s response also undermined Hutchinson’s popularisation of the previously obscure word ‘dinosaur’, which Seeley believed to be a misleading term wrongly emphasised by American researchers. Subsequently, Fallon shows how Hutchinson’s controversial attempt to publish a paper on the American dinosaur Diplodocus for the specialist Geological Magazine led him to criticise the secularity and complex style of conventional scientific articles. Hutchinson’s career exemplifies the concerns of this book.
