Three generations of Leakeys have dug in East Africa for fossil evidence that answers questions about human origins. Louis and Mary, husband and wife, began what would turn into decades of research and fieldwork, often disproving common theories and beliefs of the time. Son Richard followed in his parents' foot steps, along with his wife Meave, and made spectacular finds as well. Today, Louise, the oldest daughter of Richard and Meave, continues the family tradition with fieldwork in northern Kenya.

The Leakey family's achievements have had an enormous impact on our knowledge of human origins and evolution. This biography describes their life in detail, including their discoveries, publications, controversies, and legacy. A timeline, glossary, and bibliography of print and electronic sources supplement the material.
