In 1941, in the middle of the Second World War, the great German physicist Werner Heisenberg made a strange trip to Copenhagen to see his Danish counterpart Niels Bohr. They were old friends, and their brilliant collaboration in the twenties had begun to lay bare the mysteries at the heart of the atom. But now Denmark was under German occupation, the meeting was fraught with danger and embarrassment - and Heisenberg was burdened with a terrible secret.
Why he went to Copenhagen and what he wanted to say to Bohr are questions which have exercised historians ever since. In Michael Frayn’s multi-award-winning drama Heisenberg meets Bohr and his wife Margrethe once again to look for the answers, and to explore, just as they once had the uncertainty at the heart of the atom, the uncertainty of the human mind.
This modern classic receives its first London production since the 1998 National Theatre premiere in a completely new production by Michael Longhurst (Between Riverside and Crazy, Caroline or Change and Gloria at Hampstead).
Starring award-winning actors Alex Kingston (ER, Doctor Who) and Richard Schiff (The West Wing, The Good Doctor) as Margrethe and Niels Bohr. Further casting to be announced soon.
‘The most invigorating and ingenious play of ideas in many a year and a work of art that humanizes physics in a way no other has done.’ – New York Times
