According to Columbia Encyclopedia, the symptoms of Down syndrome were "first described in 1866 by an English physician, J. Langdon Down."
Down syndrome - albeit without this particularly moniker - has been known for many hundreds, if not thousands, of years. It was usually called Mongolism in recent centuries in the UK.
Dr. John Langdon Down was the one who did much research on the subject, and the symptoms described by him have been renamed "Down syndrome."
