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 [ca] (1855-1921), a man whose important legacies led to the founding of the Escola Massana [ca]. Julio Gibert Mateus,[6] founder, among other companies, of El Hogar y La Moda,[7] 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.
