A newly commissioned portrait of Sir Andrew Wiles, the Oxford Mathematician, has been unveiled at the National Portrait Gallery. The four-by-three foot portrait is by London artist Rupert Alexander, who has painted the Queen and members of the Royal Family.

Artist Rupert Alexander says: ‘I wanted to convey the cerebral world Sir Andrew inhabits, but rather than doing so by furnishing the composition with books or the obligatory blackboard of equations, I tried to imply it simply through the light and atmosphere. Mathematics appears to me an austere discipline, so casting him in a cool, blue light seemed apt.’

Sir Andrew Wiles by Rupert Alexander is on display in Room 38 at the National Portrait Gallery from Tuesday 14 July, Admission free.
