Maurice Klippel.

Maurice Klippel (1858-1942) was a turn-of-the-century French internist with a special interest in neurology and psychiatry. He authored numerous medical papers in these disciplines, but is best known to spine surgeons for his description, co-authored with Andre Feil, of a patient with congenital fusion of the cervical vertebrae, a condition now known as Klippel-Feil syndrome.
