What really happened when Charles Mountford led a quarrelsome team of Australian and American scientists to explore traditional Aboriginal life in Arnhem Land in 1948.

'Here was I with the status of little more than a telephone mechanic, taking out the biggest scientific expedition in history'

In this way the legendary Charles Mountford immodestly described his biggest assignment: to lead an expedition of American and Australian scientists to Arnhem Land in northern Australia, investigating traditional Aboriginal life and the tropical environment. Backed by National Geographic, the Smithsonian Institution, and the Australian government, it was also a display of the friendship between Australia and the US.

But the adventure turned out to be anything but friendly. In this compelling account, award-winning historian Martin Thomas tells how they set out with fanfare in 1948 and how quickly the expedition turned toxic. Thomas uncovers the secrets, scandals, and unlikely achievements. He also reveals how Indigenous communities, including the elders known as 'clever men', dealt with the intrusion of these foreign 'experts'.

Drawing on years of collaborative research with Arnhem Land communities, Clever Men is a poignant portrayal of colliding worlds. In this encounter between scientific hubris and the world's oldest surviving cultures, Thomas finds a story of global significance and profound long-term impacts.
