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 colleague Niels Bohr. They were old friends and collaborators, and together in the 1920s they 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 work out, just as they had once worked out the internal functioning of the atom, how we can ever know why we do what we do.

Michael Frayn is one of this country’s finest writers. Copenhagen premiered at the National Theatre in 1998, going on to the West End and Broadway and winning over 10 major international awards.

Michael Blakemore’s many collaborations with Michael Frayn include Democracy at the National Theatre and the original production of Copenhagen for which he won a Tony Award. Of his extensive London productions, 15 have earned Evening Standard or Olivier Awards.

Charles Edwards returns to Chichester to play Heisenberg. His work ranges from Downton Abbey on television to the original cast of This House and the forthcoming Absolute Hell (National Theatre).

Paul Jesson makes his Chichester debut as Bohr. His screen work includes Mr Turner and Spooks, while extensive theatre includes Wolf Hall and Bring Up The Bodies (RSC).
