Prince Philip first met the Queen at the Royal Navy training facility – because of a mumps outbreak.
Details and rare photos of the historic first meeting at Britannia Royal Naval College in Devon have been posted on social media by the Department of Defense (MoD).
On Twitter, a spokesman said: “In 1939 HRH, the Duke of Edinburgh met Her Majesty the Queen for the first time at Britannia Royal Naval College.
“The photos show the time when then Prince Philip of Greece and Denmark was hired to look after Princess Elizabeth after an outbreak of mumps that excused her not to go to church.
“One of the rare photographs is one of Princess Elizabeth and Prince Philip playing croquet.
“These photos were found in the private family album of then Captain of the College, Capt F. Dalrymple-Hamilton. The photo album came into the possession of the Britannia Royal Naval College prior to 1980.
“HRH the Duke of Edinburgh and Her Majesty the Queen were married for 73 years. Their wedding took place in November 1947.
“HRH Prince Philip, the longest serving British wife, resigned from the Royal Navy in 1952 to assist with royal duties.”
It was reported today that members of the royal family will no longer wear military uniforms at the Duke of Edinburgh’s funeral.
It is believed that the Queen decided that high-ranking kings attending the service should wear civilian clothes.
The move means the Duke of Sussex doesn’t have to act as one of the few close family members who doesn’t wear a uniform on Saturday.
Harry lost his military honorary degrees after deciding to step down as a senior working king.
