May 2020  In this episode we again return to the Bill Tutte symposium that was held at Bletchley Park in 2017, on the centenary of his birth.  As a member of the Bill Tutte Memorial Fund Claire Butterfield had by 2017 spent 4 years campaigning for more recognition for the little-known mathematical genius. For the first time we can bring you Claire’s entire talk that opened the day and in it she explores Bill’s entire life and work.   Image: ©Bletchley Park Trust 2020 #BPark, #WW2, #BletchleyPark, #Enigma, #Tunny
