Among the new publications tempting Spanish readers in 1785, alongside a comedy about jealous women, a how-to manual on forensic surgery, and a 600-page translation of the rulings of the Council of Trent, was a modest pamphlet about potatoes. Its author was an expatriate Irishman, Henry (or Enrique) Doyle. Doyle had for some decades resided in Spain, pursuing an undistinguished career in textile manufacturing. He had also drafted several essays on religious themes, with no impact whatsoever on the Spanish reading public. His writings on potatoes, however, were a phenomenal success. The 1785 pamphlet was followed in 1797 by a longer treatise issued with royal approbation at the behest of several important ministers, which was into its fourth edition by 1804. Newspapers and journals hailed Doyle as a patriotic and enlightened contributor to public happiness and seconded his ambition of extending potato cultivation across the length and breadth of Spain.
