Eugène Charles Apert (27 July 1868 – 2 February 1940) was a French pediatrician who was born in Paris.
He received his doctorate in 1897 and afterwards was associated with the Hôtel-Dieu and Hôpital Saint-Louis. From 1919 until 1934, he worked at the Hôpital des Enfants-Malades in Paris. Pediatrician Jacques-Joseph Grancher (1843–1907) and surgeon Paul Georges Dieulafoy (1839–1911) were important influences to his career. He was also a student of pediatrician Antoine Bernard-Jean Marfan (1858–1942) and collaborated with dermatologist François Henri Hallopeau (1842–1919).
Apert's medical research primarily dealt with genetic diseases and congenital abnormalities. In 1906, he documented several cases of individuals who had congenital malformations of the skull. This disorder was to become known as Apert syndrome and consists of a triad of disorders, namely craniosynostosis, syndactyly and maxillary underdevelopment.
Apert published many articles in the field of pediatrics, including an influential manual on child rearing. He was also a founding member of the French Society of Eugenics.
