| Reverse description | Portrait of mathematician and computer science pioneer Alan Turing at centre-left, rendered in intaglio against a background of binary code notation and a table of mathematical symbols referencing his foundational work on computation. The 'Bank of England' inscription appears at upper left with the denomination '50' and '£50' at upper right, and the words 'Fifty Pounds' in script at lower centre. A quote attributed to Turing reads 'This is only a foretaste of what is to come and only the shadow of what is going to be', set alongside a facsimile of his signature. |
