Down syndrome - history and terminology

The history of Down syndrome

It is almost certain that there have always been people with Down syndrome. Children with Down syndrome are seen in pictures from 1505. However, Dr John Langdon Down (1828-1896) an English physician working in Surrey was the first person to recognise Down syndrome as a 'syndrome' (a characteristic range of symptoms or features usually occurring together). The condition therefore bears his name.

Correct terminology

"Down syndrome" (rather than "Down's syndrome") is now the accepted form throughout the majority of English speaking countries worldwide. In some countries it is also known as "Trisomy 21" as this is the main form of genetic variation that causes Down syndrome.
