In 1962 Louis was visiting Olduvai when Ndibo Mbuika discovered the first tooth of "Homo habilis" at MNK. Louis and Mary thought it was female and named her Cinderella, or Cindy. Phillip Tobias identified Jonny's Child with it and Raymond Dart came up with the name "Homo habilis" at Louis' request, which Tobias translated as 'handyman'. It was seen as intermediary between gracile "Australopithecus" and "Homo".
