The Duchess of Cambridge told Lady Marion Body, a former colleague of her late grandmother's, that it was "so moving" to meet her and to visit Bletchley Park, the famous "spy school" during World War II.
The Duchess of Cambridge has met a code-breaker who worked alongside her grandmother at Bletchley Park during World War Two.
Kate shook hands with Lady Marion Body and talked about her grandmother Valerie Glassborow, who worked as a civilian member of staff, probably as a duty officer.
The Duchess of Cambridge is due to visit Bletchley Park where she will meet with a code-breaker who worked with her grandmother during the Second World War.
Code-breaker veteran Lady Marion Body recalls working alongside the Duchess' paternal grandmother Valerie Glassborow at the famous 'spy school', where codebreakers were credited with shortening the war by at least two years.
Miss Glassborow, as she was known before marrying Kate's grandfather Peter Middleton, worked as a civilian member of staff, probably as a duty officer, alongside her twin sister Mary.
Kate's solo visit will mark a year-long restoration project at the Buckinghamshire site.
A website has been created so contributions made to the groundbreaking Bletchley Park code-breakers can be seen.
The site allows people from all over the world to learn about veterans' roles in the code-breaking efforts.
Search options on the website include an individual veterans' name, section, location or building.
It is hoped that the more veterans and their families tell the Bletchley Park Trust about they work they carried out in the Second World War, the richer and more in-depth the website becomes.
