This article recounts an untold chapter in the life of archaeologist Froelich Rainey, specifically his ambition to collaborate with Soviet scholars and deploy his personal networks to foster mutual understanding across the Iron Curtain during the height of the Cold War. The picaresque and implausible life of Rainey, who entered wartime Vienna in the turret of a B-52 bomber and was a State Department consultant with CIA connections, frantic anti-communist and advisor to Henry Kissinger, reveals just what was at stake for research in the frozen north. Here, I uncover Rainey’s work on ice—from his archaeological explorations in Alaska and his vision for a network of Arctic archaeologists to his internationalist aspirations for world peace. Without doubt, Rainey was a fascinating character, but he also occupied a position from which a wide range of values can be excavated—about politics, security, race and global order in mid-century transitions.
