[José Ignacio Bartolache y Díaz de Posada: his contributions to medicine].

During 18th century in New Spain, the strong link between religion and science hindered scientific growth. Conservatism and scholasticism pervaded educational institutions. Within this restricted context, a scientific community conformed mainly by creoles fulfilled their desire and need to know more as they had access to European books, which allowed erudite leading figures, such as Dr. José Ignacio Bartolache y Díaz de Posada, propel innovative ideas in medicine and pharmacy. Dr. Bartolache was considered sacrilegious and scandalous by the ecclesiastical authorities of that epoch. He favored the performance of human body dissections to improve medical education, as well as the anatomical proposals of Vesalius against Galeno's classical anatomy. He contributed to the dissemination of knowledge as he created the first medical magazine in the American continent: El Mercurio Volante (The Flying Mercury); he also printed medical pamphlets and flyers, some of which were published in Nahuatl and Spanish, as the prescriptions for martial pills, reformulated by himself. Physician ahead of his time, he was characterized by his professional humanism and the comprehensive treatment of patients; he emphasized the rational use of medications, without distinction of social class. His sensitivity allowed him to bring medical knowledge and treatment of illnesses closer to the most vulnerable. Another of his contributions, ahead of his time, was the recognition he gave women for the intelligence and ability they showed, equal to men, when accessing education.
