From the day after he was born, photographers have documented the Duke of Cambridge's life in intimate detail. Here is a selection of the very best photos from key moments in his life: births, deaths, marriages—and even vacations.

In 2014, William put his helicopter-flying skills to work with the East Anglian Air Ambulance service.

Last November, he told the BBC that he found some elements of the job distressing. "I worked several times on very traumatic jobs involving children," he told said.

"After I had my own children, I think the relation between the job and the personal life was what really took me over the edge, and I started feeling things that I have never felt before," he continued. "Talking was really important, but even that wasn't quite enough for one particular incident for me."
