[Salvador Armendares: second generation Spanish refugee and pioneer of human genetics in Mexico].

This paper gives an analysis of Dr. Salvador Armendares' exile and professional career, with the aim of exploring the relation between the intellectual contributions of the second generation of Spanish refugees in Mexico and the origins of medical genetics in that country. The thesis is that the emigration of European refugees due to political issues, where eugenic values were exalted, paradoxically facilitated the establishment of medical genetics in Mexico. Interpretation of cultural, political, and social factors contributes to the analysis, avoiding Eurocentric and expansionist narratives.
