Down Syndrome Awareness Month - Day 26

John Langdon Down, an English physician, published scholarly work describing Down Syndrome in 1866 that earned him the reputation at the "father" of Down Syndrome. Down Syndrome is named after him. Dr. Down and his wife dedicated their entire lives to caring for people with Down Syndrome. In 1958, a geneticist named Jerome Lejeune discovered that Down Syndrome is caused due to the presence of an extra 21st chromosome. He called the disorder trisomy 21. Professor Jerome also dedicated his life to researching Down Syndrome.
