Antonio Vallejo-Nájera

Antonio Vallejo-Nájera (1889–1960) was a Spanish psychiatrist. He was interested in eugenics and proposed a link between Marxism and intellectual disability, something he sought to prove through experimenting on Republican prisoners. His ideas led to the thefts of many Spanish newborns and young children from their left-wing parents in Francoist Spain; as many as 30,000 children were taken from leftist families and placed with nationalist families. Vallejo-Nájera was rewarded for his assistance during the Spanish Civil War and he became a leading figure in Spanish psychiatry.
