The Royal Society of London for the Improvement of Natural Knowledge, known simply as The Royal Society, claims to be the oldest learned society still in existence. It was founded in 1660, only a few months after the Restoration of King Charles II, by members of one or two either secretive or informal societies already in existence. The Royal Society enjoyed the confidence and official support of the restored monarchy. The "New" or "Experimental" form of philosophy was generally ill-regarded by the Aristotelian (and religious) academies, but had been promoted by Sir Francis Bacon in his book The New Atlantis.
Robert Boyle refers to the "Invisible College" as early as 1646. A founding meeting was held at the premises of Gresham College in Bishopsgate on 28 November 1660, immediately after a lecture by Sir Christopher Wren, at that time Gresham Professor of Astronomy. At a second meeting a week later, Sir Robert Moray, an influential Freemason who had helped organize the public emergence of the group, reported that the King approved of the meetings. The Royal Society continued to meet at the premises of Gresham College and at Arundel House, the London home of the Dukes of Norfolk, until it moved to its own premises in Crane Court in 1710.
A formal Royal Charter of incorporation passed the Great Seal on 15 July 1662, creating "The Royal Society of London", with Lord Brouncker as the first President, and Robert Hooke was appointed as Curator of Experiments in November 1662. A second Royal Charter was sealed on 23 April 1663, naming the King as Founder and changing the name to "The Royal Society of London for the Improvement of Natural Knowledge".
