Abstract

Fifty years ago, I was co-author of the first paper asserting the presence of a supernumerary chromosome in Down’s syndrome (called « mongolism » in France at that time). This first autosomal chromosomal abnormality was called Trisomy 21. It seemed to me historically interesting to bring my own testimony as an actor in this discovery.
