Leo Testut (22 March 1849 – 16 January 1925) was a French physician and anatomist, born in Saint-Avit-Sénieur, Dordogne.
He was named Professor of Anatomy of the Bordeaux School of Medicine and continued his investigations in anthropology in other universities.
He contributed over 90 publications on anatomy, anthropology, prehistory and history, but his most noteworthy achievement has been as author of Traité d´anatomie humaine, a complete, well-written, and well-illustrated work of anatomy composed of four volumes that continues to be used in many countries to the present day.
He collected the material published from personal notes and drawings after having failed anatomy exams several times during medical school, until he finally passed.
