Klinefelter syndrome was first described in 1942 by Dr. Harry Klinefelter, an endocrinologist at Massachusetts General Hospital. He published a case study of nine adult men with a common set of symptoms involving hypogonadism. At the time, chromosomes had not yet been discovered.
In 1956, Dr. Joe Hin Tjio and Dr. Albert Lavan took the research further to determine the factors that made those men with Klinefelter's Syndrome dissimilar from normal adult males through genetic research (Klinefelter Syndrome, 2006; Schoenstadt, 2006).
