“My grandfather worked in advertising for Rowntree before the war,” says Giles, 47.

“I didn’t know much about Joseph, but now, looking back, I wish I had spoken to my grandfather more about him and his relationship with Joseph – it would be great to know more.”

Despite his business connections, Giles worked as a buyer for a large retailer before being approached by recruiters to apply for a job at Nestlé.

He says he did not reveal his family history to many of his colleagues.

“I grew up on a farm, a far cry from chocolate,” he says.

“It was always important for me to prove that I did it unintentionally, and there was no favoritism involved.

“I tend to keep it quite quiet.”
