30 years ago today Andrew Wiles told an excited audience at the Isaac Newton Institute in Cambridge that he had proved Fermat's Last Theorem, arguably the greatest puzzle in mathematics, a 300 year-old mystery.

And so began a story of wonder at the achievement, followed by despair at the discovery of an error, the elation of a final proof, a TV documentary, a biography, a musical, prizes galore and the naming of a building where, 30 years later, in the Andrew Wiles Building in Oxford, Andrew Wiles continues his research.
