Mary Leakey (6 February 1913 – 9 December 1996) would have been 100 last Wednesday. She spent a great deal of her life at Olduvai Gorge in eastern Africa with her husband Louis. Olduvai Gorge is seen as the cradle of humanity, though there would be some who would disagree with that. As far as evolution goes however you’ve got to start somewhere. It is still good though to recognise a woman who actually began as a so-called amateur and ended up being an expert in her subject (her son still continues the family tradition).
So, to all explorers and archaeologists who work ‘in the field’ a toast, and a belated happy birthday to Mary Leakey.
