Objetives: The main aim of our work is to highlight the importance of Chamorro’s discoveries in the fields of endocrinology, gynaecology, reproduction and oncology. Methods: Evaluation of the bibliometric impact of Chamorro’s work using Google Scholar, PubMed, Scopus and Gallica. Results: Between 1937 and 1945 Chamorro carried out important research work, the results of which provided valuable discoveries about the activity of the main endocrine glands. Discussion: To achieve our objective, Google Scholar has been the most profitable metasearch engine from a practical point of view, having recognized almost all of the articles published by Chamorro, although having ignored some of them it could be thought that the overall impact of this author is higher than that which has been found. Conclusions: These findings were reflected in the most prestigious journals and widely disseminated in U.S. research institutions, amongst others. In Spain, however, they were ignored. Maybe it’s time to spread it.
