"Mr Roberts, of Hampshire, was among four founder members of the Testery section tasked with breaking the German High Command's Tunny code," BBC News reports. "The decrypts are credited with helping shorten the war by at least two years. Capt Roberts worked at Bletchley Park, Buckinghamshire, until the end of the war then spent two years at the War Crimes Investigation Unit, before moving on to a 50-year career in marketing and research."
"Bletchley Park's '4T's' include the Testery as a whole, and three colleagues responsible for major discoveries -- Alan Turing who broke the naval Enigma; Bill Tutte who broke the Tunny system to help shorten the war; and Tommy Flowers, who designed and built the Colossus, which sped up some stages of the breaking of Tunny traffic," Huffington Post UK reports. "Roberts, from Hampshire, has spent the last four years campaigning for his former colleagues to be recognised."
"By the end of the war, with Colossus, the Testery group was breaking 90 percent of the intercepted traffic given to them," Infosecurity reports. "After the war, General Dwight D. Eisenhower said that 'Bletchley decrypts shortened the War by at least two years.' During this period the war was causing the death of up to 10 million people per year. It could be suggested, then, that Capt Jerry Roberts MBE was instrumental in saving the lives of 20 million people."
