Frank Oppenheimer followed in his famous brother’s footsteps-growing up in a privileged Manhattan household, becoming a physicist, working on the atomic bomb. When the brothers careers were destroyed by the Red Scare, Frank took it as an opportunity to come into his own. After ten years of exile, Frank emerged to create his Exploritorium. More than an institution, it was a revolution that transformed museums. Cole, a friend and colleagues of Frank’s, draws from letters, documents, and extensive interviews to write this very personal and inspiring story.
