Copenhagen is an exploration of the meeting in 1941 between Bohr and Heisenberg. As two of the pre-eminent physicists of their time, they also shared a very close, almost familial relationship. But coming for opposite sides of the war, their friendship was destroyed by the secret meeting that was instigated by Heisenberg. What was it that Heisenberg wanting so desperately to convey to his well-respected colleague? Whatever it was lead to Bohr cutting all communication with his former partner. The play supposes a meeting long after the three characters are dead -- they come together once again to tackle what happened. Bohr's wife, Margrethe, acts as a commentator and referee as the two men once more cautiously approach the meeting. A different ending to the meeting could very well have changed the outcome of the war. This material is deep and profoundly disturbing. It is meant for mature audiences who don't need to have things blown up in front of them to enjoy a theatrical experience!
