The 100th anniversary of the birth of British archaeologist and anthropologist Mary Leakey is celebrated with a Google doodle depicting her at work on a dig.
Leakey was born on February 6, 1913 and died in December 1996. She changed her name when she married Louis Leakey, also an anthropologist, in 1936. Her maiden name was Nicol.
She is best known for her discovery of the first fossilised Proconsul skull, the skull of an extinct ape which is believed to be an ancestor of humans. Much of her work took place at Olduvai Gorge in Tanzania.
