Cornelia Catharina de Lange
Cornelia Catharina de Lange was a Dutch pediatrician. Cornelia de Lange syndrome is named after her.Life
Born in Alkmaar, De Lange graduated from the University of Amsterdam in 1897 and began her general practice. However, because pediatrics did not exist as a specialty in the Netherlands, De Lange moved to Switzerland, where she worked in the children's hospital in Zurich under Oskar Wyss. In the early 1900s De Lange became an acclaimed specialist and attained a position in Amsterdam's Children's Hospital. De Lange worked in all aspects of pediatrics. During her 50 years of practice she collected multiple observations of pediatric disorders. De Lange also became interested in congenital disorders and their pediatric relevance as theories on human genetics developed during the 1920s and 1930s. In 1933, De Lange described what she called "typus degenerativus Amstelodamensis" in two children, which became known as Cornelia de Lange syndrome.
