The riveting story of the pioneers who redefined conceptions of ‘normality’ in the early twentieth century.

Under the guiding eye of cultural anthropologist Franz Boas, these scientist-explorers - most of them women - made intrepid journeys into far-flung communities all over the world, where they documented radically different social approaches that overturned Western assumptions about human diversity and challenged the era’s scientific consensus.

Here, the boundary-breaking lives and achievements of Margaret Mead, Ruth Benedict, Ella Deloria and Zora Neale Hurston are brought fully into light for the first time, showing how their trailblazing discoveries helped shape the moral universe we inhabit today.
