LONDON (Reuters) - Prince Charles, the oldest and longest-serving heir-to-the-British throne, celebrates his 70th birthday on Nov. 14.

Here are some facts about Charles.

* Born in Buckingham Palace at 9.14 p.m. on Nov. 14, 1948, Charles is the eldest son of Queen Elizabeth and Prince Philip.

* He was the first heir to go to school and university, being educated at Gordonstoun school in northern Scotland and Trinity College, Cambridge, where he obtained a second class history degree. Charles went on to serve in the Royal Air Force and the Royal Navy. He qualified as a helicopter pilot.

* His investiture as the Prince of Wales took place on July 1, 1969 at Caernarfon Castle.

* After leaving the armed forces, Charles set up the Prince's Trust in 1976 to help disadvantaged young people in the United Kingdom, using his Royal Navy severance pay of 7,400 pounds to fund a number of community initiatives.

About 750,000 people watched the ceremony live on television and a crowd of more than 500,000 lined the route between Buckingham Palace and the cathedral. The couple had two sons, William, born in 1982 and Henry, known as Harry, born two years later.

* Charles and Diana were divorced in August 1996 after years of acrimonious marital problems. Diana blamed Charles for his refusal to end his affair with his long-term lover, Camilla Parker Bowles.
