Peace symbol turns 50

It started life as the emblem of the British anti-nuclear movement but it has become an international sign for peace, and arguably the most widely used protest symbol in the world. It has also been adapted, attacked and commercialised.

It had its first public outing 50 years ago on a chilly Good Friday as thousands of British anti-nuclear campaigners set off from London's Trafalgar Square on a 50-mile march to the weapons factory at Aldermaston.

The demonstration had been organised by the Direct Action Committee Against Nuclear War (DAC) and the Campaign for Nuclear Disarmament (CND) joined in.

Gerald Holtom, a designer and former World War II conscientious objector from West London, persuaded DAC that their aims would have greater impact if they were conveyed in a visual image. The "Ban the Bomb" symbol was born.

He considered using a Christian cross motif but, instead, settled on using letters from the semaphore - or flag-signalling - alphabet, super-imposing N (uclear) on D (isarmament) and placing them within a circle symbolising Earth.

The sign was quickly adopted by CND.

Holtom later explained that the design was "to mean a human being in despair" with arms outstretched downwards.
