For years, Andre Geim was known to the world as a Nobel Prize-winning Dutch physicist, which suited both him and the Dutch just fine. He is still a Nobel Prize-winning physicist, but now, according to the government of the Netherlands, he is no longer Dutch. He said he was informed that he was no longer a Dutch citizen and must hand his passport over at the embassy in London or face consequences from Interpol, because the Netherlands sharply restricts dual citizenship. “Personally, I consider myself a Dutch-British Nobel Prize winner (in this order),” he said in an email. “The history and my time living and working in the Netherlands are very close to my heart.”
