Prince Nikolaos, a photographer and environmental activist, was born into the Greek royal family shortly before the monarchy was abolished in 1974.
The royal dabbled in various professions before he became a photographer.
In 1995 he worked as a production assistant at Fox News in New York. He didn't want to be treated any differently because of his royal status, so he dropped his royal title and used a pseudonym.
"Nobody knew, apart from the director of course. It was great, I was treated just like anybody else," Nikolaos previously told Insider.
However, photos of Nikolaos at his brother Crown Prince Pavlos' royal wedding soon got back to the newsroom and his coworkers discovered who he was.
"When they found out, they had formed their opinion of me, good or bad, one way or the other, but it wasn't influenced by my background. Which is how it should be," Nikolaos added.
