Prince Philip, the 91-year-old husband of the UK's Queen Elizabeth II and the grandfather of Prince William, was recently hospitalized as a "precautionary measure," Buckingham Palace announced on Wednesday, August 15.
Officials did not provide a reason. The elder prince, known as the Duke of Edinburgh, Earl of Merioneth and Baron Greenwich, was taken to Aberdeen Royal Infirmary, located in Scotland, where he had been staying with his wife.
"We are waiting for a full medical assessment," a palace spokesperson told the UK newspaper The Evening Standard.
Philip suffered several ailments in recent months. In June, he was hospitalized for several days to treat a bladder infection after spending four hours on a barge in stormy weather during his wife's Diamond Jubilee Thames River Pageant, one of the events marking the anniversary of her 60-year reign. On Dec. 23, 2011, the day before Christmas Eve, he underwent minor heart surgery.
The prince appeared to be in good spirits during visits to a country club and to engineering and construction company A J Wells and Sons in Newport on the Isle of Wight on Monday. He also attended the Opening Ceremony of the London Olympics with the Queen on July 27.Philip was born on June 10, 1921 and is the only son of Prince Andrew of Greece, whose grandfather was King Christian IX of Denmark. Philip became a naturalized British citizen and renounced his former royal title in 1947, during World War II. That year, he married Elizabeth, his distant relative. Both are great-great grandchildren of Queen Victoria.
Philip and the Queen, informal ruler of the United Kingdom by birthright, have four children - Prince Charles, who is first in line to the throne and the father of princes William and Harry, Princess Anne, Prince Andrew and Prince Edward.
