Jaroslav Madlafousek, Ph.D., C.Sc. (1922-2008) was a Czech comparative psychologist, physiologist, ethologist, and sexologist. He made extremely important empirical contributions to the study of sexual behavior in both humans and rats, among others, helping to pioneer the use of plethysmography to measure genital sexual arousal in men. Here, we present a biography of his life, his struggles against the dictatorships that ruled his country, and his scientific and clinical achievements, many of which were decades ahead of their time but still remain unknown to researchers outside Czechia. We include a complete bibliography of his scientific contributions in both Czech and English journals in the supplementary material.
Pfaus et al. (2025) studied this question.
