Tonight there will be a special tribute to Second World War code-breaker Alan Turing on Salford Quays. Two of the most powerful lasers in the world will beam out 'thank you' in morse code two miles into the sky in recognition of the Wilmslow mathematician.
Turing was a mathematical genius and the father of the modern computer, much of his ground breaking work was conducted at The University of Manchester.
Artist Craig Morrison created ‘Thank You’ in memory of all the men and women who served in the First and Second World War, and to thank Alan Turing for the many lives he helped to save.
The light show will take place for the next week and will form the centre-piece of this year’s Manchester Histories Festival.
