Editorial Molino

Pablo del Molino Mateus was the son of a property registrar, Pablo del Molino Martín (Cartagena, Spain) and Concepción Mateus Massana (Valladolid, Spain). Concepción Mateus inherited in 1923 from his relative Agustí Massana i Pujol (1855-1921), a man whose important legacies led to the founding of the Escola Massana. Julio Gibert Mateus, founder, among other companies, of El Hogar y La Moda, proposed to his first cousin Concepción Mateus to invest the inheritance received in shares of a publishing house that he promoted, Editorial Juventut. In this way, Concepción Mateus and her son Pablo del Molino Mateus became part of the company's board of directors, led by José Zendrera. In 1930 Pablo del Molino was appointed deputy director of Editorial Juventud. Editorial Juventud promoted at that time the collection La Novela Rosa, dedicated to sentimental and romance narratives.

In 1933, Pablo del Molino resigned as deputy director of Editorial Juventud to found Editorial Molino. Pablo del Molino favored publishing a type of adventure and crime novel from the Anglo-Saxon world, in front of the editorial line of Editorial Juventud, more focused on adventures aimed at a young audience by French and German authors. Editorial Molino published its first title already on November 10, 1933, entitled El Ruiseñor del Noroeste (Singer in the Wilderness), by William Byron Mowery, as the first number of the Biblioteca Oro (Blue Series). That same year he launched the Serie Popular Molino4, and the collection of children's stories Marujita.

Editorial Molino specialized in a genre that could be defined as popular: adventure novels, detective novels, stories of distant landscapes or in bygone times, and made its logo popular: a black windmill on top of two books, one on top of the other.
