Mary Leakey — British Scientist born on February 06, 1913, died on December 09, 1996

Mary Leakey was a British paleoanthropologist who discovered the first fossilised Proconsul skull, an extinct ape now believed to be ancestral to humans. She also discovered the robust Zinjanthropus skull at Olduvai Gorge in Tanzania, eastern Africa. For much of her career she worked with her husband, Louis Leakey, at Olduvai Gorge, where they uncovered fossils of ancient hominines and the earliest hominins, as well as the stone tools produced by the latter group. Mary Leakey developed a system for classifying the stone tools found at Olduvai. She discovered the Laetoli footprints, and at the Laetoli site she discovered hominin fossils that were more than 3.75 million years old... (wikipedia)

The first money I ever earned was for drawing stone tools.
I had never passed a single school exam, and clearly never would.
I'd rather be in a tent than in a house.
Basically, I have been compelled by curiosity.
You only find what you are looking for, really, if the truth be known.
