This article presents the perspectives of the physician and politician Jaime Vera y López (1859-1918), co-founder of the Spanish Socialist Workers' Party, on the medical profession, medical practice, and healthcare systems. It compares the Report (Informe) that he presented to the Comisión de Reformas Sociales (1884) with his later writings published in the socialist press ("Farmacia y cooperación obrera,, 1914 and "La locura en los niños. Camino del remedio", 1916). We observe the discrepancies between the political-programme documents and the articles centring on professional questions and highlight how his theoretical focus is modified when applied to matters of medical practice.
