Mary Leakey (1913-1996) was a paleoanthropologist who made several important discoveries related to the evolution of humanity. In 1948 she discovered the first ever fossilised Proconsul skull, an extinct ape and an early ancestor of humans.
Even though she showed a great interest in archaeology from an early age and wanted to apply to Oxford, she was discouraged to do so, and was turned away from several excavation sites until finally being allowed to work. Throughout her career she discovered fossils and stone tools belonging to different species of early hominids, some of them more than 3.75 million years old. She discovered fifteen new species and one new genus of animal.
