President John F Kennedy’s “Ich bin ein Berliner” speech was a message of solidarity to West Berlin at the height of the Cold War. Some 50 years on, previously unseen photographs of his visit to the city have the power to recreate the drama of the moment.

There’s no doubt that Kennedy’s speech was one of the great speeches of history.

It’s hard to imagine those pressured times now, but 50 years ago the world was divided into two blocs of East and West, each with an arsenal of nuclear rockets pointed at the other.
