Jérôme Lejeune

Jérôme Jean Louis Marie Lejeune was a French pediatrician and geneticist, best known for his work on the link of diseases to chromosome abnormalities, most especially the link between Down Syndrome and trisomy-21 and cri du chat syndrome, amongst several others, and for his subsequent strong opposition to, in his opinion, the improper and immoral use of amniocentesis prenatal testing for eugenic purposes through selective and elective abortion. He is venerated in the Catholic Church, having been declared Venerable by Pope Francis on 21 January 2021.
