John Langdon Down

John Langdon Down was a British physician best known for his early work in identifying and describing Down syndrome, a genetic disorder caused by the presence of an extra chromosome 21. Born in 1828, he dedicated much of his career to the care and education of individuals with intellectual disabilities, advocating for their rights and inclusion in society. His seminal paper, published in 1866, laid the foundation for our understanding of the condition that would later bear his name. Down passed away in 1896, but his legacy continues to impact the fields of medicine and special education.
