Countess of Wessex Prince Philip and Queen Elizabeth
"She fell in love at age 18 and she never looked at anyone else," Sally Bedell Smith, author of Elizabeth the Queen, told PEOPLE.
As depicted on Netflix's smash The Crown, Elizabeth fought to marry Philip against some opposition from others in The Firm.
"Some were very concerned. The line was slightly tenuous at that point," the late Sir Edward Ford, who previously served as an assistant royal secretary, told PEOPLE. "So, it was only natural that the older generation — friends of the King like Lord Salisbury — were concerned that who the Queen was with was totally and utterly suitable. So they were sniffing around to see what he was like."
Perhaps part of what attracted the Queen to Philip was that he didn't try too hard to impress others, Ford noted.
"He was a perfectly natural young sailor and very much in love with the girl of the house," Ford said. "But he would not in any way fawn on the elders and say, 'What a suitable husband I am going to be.' He was very much his own man."
The couple were married for 73 years until Philip's death in April 2021 at 99 years old. Queen Elizabeth died at age 96 on Sept. 8, 2022, and remained devoted to her husband's memory until the very end.
