Professor of the VCU academic and scientific life in 1891, Dr. Hernandez returns from Europe, and in November of that year, began its activity as a teacher in the chairs of Normal and Pathological Histology, Experimental Physiology and Bacteriology, University of Central Venezuela (UCV), founder of both, it is noteworthy that on completion of their graduate studies in Paris and Berlin it was delegated the responsibility for acquiring the resources of the Venezuelan state and essential materials needed to install “The Laboratory of Experimental Physiology” in Caracas and the acquisition of literature that is required for the opening of the chairs mentioned in the UCV, who turned hard work, honesty, and efficiency of his own person.

Not only was the founder of the Chair of Bacteriology, since it also was the first person to Venezuela to post a job of that discipline, called “Elements of Bacteriology in 1906. rmation. The chair of bacteriology was first established in America. It starts with him when the real scientific and educational teaching, based on lessons explanatory, with observation of vital phenomena, systematic experimentation, vivisection practices and laboratory tests.Microscope introduced and taught their use and management colored and cultured microbes made known Virchow’s cell theory. It was also a great physiologist and an eminent biologist, because he knew the physics, chemistry and mathematics, basic sciences and fundamental tripod on which rests the whole dynamic animal. The practical applications of those experiences, he learned to use to serve the highest goal of medicine, which is none other than heal the sick and protect life. His educational work was interrupted twice. The first when he decided to become religious in the monastery the order of St. Bruno at La Cartuja de Farneta, which he reached on 16 July 1908, and returned on 21 April 1909, so that in May of that year resume his academic activities at the university.The second time that their teaching was interrupted from the first of October 1912 when the dictatorship of G mez decreed the closure of the university, as it had been against this tyrant.
