Prince Philip will retire this fall from his royal duties, Buckingham Palace announced Thursday.

Philip, the husband of Queen Elizabeth II, will attend previously scheduled engagements until August, but won’t accept invitations after that, a palace spokesman said, adding the decision was made by the 95-year-old Duke of Edinburgh and supported by the queen. Elizabeth, who is 91, “will continue to carry out a full program of official engagements,” the statement said.

Philip is known for both his off-the-cuff remarks and his sometimes embarrassing gaffes. At an event in London on Wednesday, he referred to himself as the “world’s most experienced plaque unveiler.”

Some of his best quotes:
