Credit to an engineer
• YOU write that the “Bombe” code breaking machine was devised by Alan Turing (WWII code cracker’s secret life, November 12).
Turing was not an electrical engineer but a superb mathematician who used the vast amount of material coming from the machine to break the Enigma code. But credit should go to Tommy Flowers, a brilliant Post Office engineer who devised and built the machine that Turing used. Am I wrong?
