Cornelia Catharina de Lange (1871 – 1950) was a Dutch pediatrician.
de Lange was at the forefront of education for women in the Netherlands. She fought the prejudice against women in the 1800s an era that deemed the medical profession inappropriate for women. As secretary for the Dutch Association for the Protection of Infants, she worked hard to establish health care centers for infants and wrote books and brochures about child care for a wider audience.
Cornelia de Lange made significant contributions in paediatric neurology. She undertook her own pathological and histological studies and published several books as well as some 250 papers.
Dr. de Lange’s contributions to the medical field earned her a knighthood from the Dutch government in 1947.

Cornelia de Lange syndrome (CdLS)
Cornelia de Lange syndrome is a developmental disorder that affects many parts of the body. The features of this disorder vary widely among affected individuals and range from relatively mild to severe. This multisystem malformation syndrome is recognized primarily on the basis of characteristic facial dysmorphism (low anterior hairline, arched eyebrows, synophrys, anteverted nares, maxillary prognathism, long philtrum, thin lips, and ‘carp’ mouth) in association with prenatal and postnatal growth retardation, mental retardation and, in many cases, upper limb anomalies. [aka Brachmann-de Lange syndrome]
CdLS is caused by a mutation in one of severn genes which code for the cohesin complex; a group of proteins essential in prenatal development. Inheritance is in a autosomal dominant or X-linked manner affecting between 1 in 10,000 – 30,000 children. Diagnosis is either made clinically based on the classical characteristics or by genetic testing.
Children with this disease are expected to reach adulthood and there are reported cases of individuals over 50 years of age with the condition. Management incorporates a multidisciplinary team approach and varies depending on the symptoms each patient presents with. It may include nutritional supplements, medications to prevent seizures and surgery to treat skeletal, gastrointestinal or cardiac abnormalities. Screening for common malformations (including cardiac and renal) and ongoing surveillance for complications of the disease is important.
1916 – The German physician, Winfried Robert Clemens Brachmann (1888–1969), provided the first documentation of the condition in his in a 19-day old infant who died of pneumonia while he was practicing at the Children’s Hospital of Dresden [1916; 84: 225–235].
1933 – de Lange described the condition following observations she had made in two unrelated girls. Not venturing to give the syndrome her own name she called it Typus Degenerativus Amstelodamensis, using the old name of the town where the children lived. In 1938 de Lange published a second paper describing further cases and follow up of the original children with the syndrome.
Cornelia de Lange medal: On November 29, 1985, the first Cornelia de Lange Medal was awarded by the Dutch Society for Pediatric Neurology to Dr Jean Aicardi (1926-2015). The medal was designed by Prof. E. Claus, affiliated with the National Academy of Visual Arts in Amsterdam. The image of Cornelia de Lange was chosen because she was the first in the Netherlands to show a profound interest in neurological syndromes in childhood.
The Cornelia de Lange Syndrome (CdLS) Foundation: American non-profit organization that has served individuals with CdLS and their families since 1981. The Foundation’s mission is reflected in its slogan: Reaching Out, Providing Help, and Giving Hope.

…dan geloof ik, dat de kinderarts de zorgeloosheid van het kind uoor een wijle tot de zijne ban maken. Dat hij kan fladderen met de vlinders, kan dartelen met de lammeren, kan kraaien met de zuigelingen, dat in hem iets is, en iets blijfi van de eeuwige jeugd.de Lange, 1932
