In 1959 they decided to excavate Bed I. While Louis was sick in camp, Mary discovered the fossilized skull OH 5, which Mary called "Our Man", and became "Dear Boy" and "Zinj." The question was whether it was a previous genus discovered by Robert Broom, "Paranthropus", which Broom had taken not to be in the human line, or a different one, in it. Louis opted for Zinj, a decision opposed by Wilfrid Le Gros Clark, but one which attracted the attention of Melville Bell Grosvenor, president of the National Geographic Society. That contact resulted in an article in "National Geographic", and a hefty grant to continue work at Olduvai.
