Australian physician, paleontologist; in 1924, Dart discovered and described the Taung child
(Australopithecus africanus), a fossil australopithecine
found at a quarry site
in what was then Botswana; following criticism by Keith, Dart withdrew from the field but, after Robert Broom and John T. Robinson described further discoveries, he resumed his avocation and produced a steady flow of new fossils
and publications through the 1960s. Dart also authored Adventures with the Missing Link
(1959). Viking Fund medallist (1957).
