Jean-François Calot (17 May 1861 – 1 March 1944) was a French surgeon best known for describing treatment of curvature of the spine in Pott's disease. He also described a method of treating tuberculous abscesses and defined Calot's triangle.
Calot was born in a farmer family of six children and spent his childhood in Arrens-Marsous, France. He received his bachelor's degree in 1880 at Saint-Pe de Bigorre and in 1881 moved to Paris, where he worked as a tutor to pay for his university education. While still a student he described Calot's triangle in his doctoral thesis, defended on 12 December 1890. He then worked as a surgeon at l'Hôpital Rotschild and l'Hôpital Cazin-Perrochaud in Berck. He described his technique for treating Pott's disease of the spine in a paper he read to the Academy of Medicine in Paris in 1896. Much of his work later in his career was in orthopaedic surgery, particularly the treatment of war injuries;[1] he founded the Institut orthopédique de Berck in 1900.
Callot married Marie Bacqueville (1870–1934), and together they had four daughters.
