As Queen Elizabeth II's husband, Prince Philip lived his life in the spotlight. The former Duke of Edinburgh died on April 9, 2021, at the age of 99, just two months shy of his 100th birthday. And according to one royal biographer, the very active Prince Philip reportedly needed one thing to help him deal with his "pent-up frustrations."
In the book The Last Queen: Elizabeth II's Seventy Year Battle to Save the House of Windsor, royal biographer Clive Irving discussed how Prince Philip handled living in his wife's shadow.
