Evening all! I'm here to beg a little help on behalf of a friend & would appreciate any ideas ... My friend would love to find out more about her late father's role in WWII. When she asked him about it many years ago, he replied: 'I can't tell you what I did, I signed the Official Secrets Act'. She reckons he wasn't military (but isn't 100% sure) as his eyesight wouldn't have been good enough to pass the physical. She describes him as 'a math genius' who loved puzzles - but he's not on the list of people who worked at Bletchley Park. I know it's a long shot, so I'm not hopeful of any positive replies, but if anyone has any suggestions of where to look or who to ask, I'd be very grateful! In case it helps: he was: Ronald James Willett Born: September 8 / 9th 1920 or 1926 in London Thanks!
