(Reuters) - Here are some key facts about Queen Elizabeth's husband, Prince Philip, who turns 90 on Friday.
* Prince Philip of Greece and Denmark was born on a dining room table on the Greek island of Corfu on June 10, 1921, the fifth child and only son of Prince Andrew of Greece.
* Philip's parents went into exile when he was 18 months old. They sailed from Corfu with him sleeping in a cot made hurriedly from orange boxes.
* He was educated at Gordonstoun, a tough school in Scotland, where his son, Prince Charles was later an unwilling pupil, and became a naturalized British citizen, looking and sounding every bit the English gentleman.
* Philip joined Britain's Royal Naval College at Dartmouth, southern England, as a cadet, in 1939. He graduated top of his class and served on battleships, cruisers and destroyers during World War Two. He was mentioned in despatches, took part in the Allied landings in Sicily and was in Tokyo Bay when the Japanese surrendered in 1945.
* Princess Elizabeth and Prince Philip first met at the 1934 wedding of Prince Philip's cousin, Princess Marina of Greece, to The Duke of Kent, who was an uncle of Princess Elizabeth.
* They were married at Westminster Abbey on November 20, 1947 in a spectacular ceremony attended by statesmen and royalty from around the world. Sixty years later, they marked their wedding anniversary with a service at London's Westminster Abbey.
* He continued his naval career until 1951, then took indefinite leave and devoted himself full time to public duties when Elizabeth became queen a year later.
* In 2010 Buckingham Palace announced that Philip would cut back his workload when he turned 90, stepping down from roles with more than a dozen organisations. The duke would still be involved with more than 800 organisations.
* In a busy 2011 so far, both the Queen and her husband celebrated the wedding of their grandson Prince William to Kate Middleton. They hosted a party at Buckingham Palace but left the younger crowd to dance into the early hours, media reported.
* They also participated last month in the first visit to the Irish Republic by a British monarch since King George V in 1911.
