- On 28 November 1660, the 1660 committee of 12 announced the formation of a "College for the Promoting of Physico-Mathematical Experimental Learning", which would meet weekly to discuss science and run experiments. At the second meeting, Sir Robert Moray announced that the King approved of the gatherings, and a royal charter was signed on 15 July 1662 which created the "Royal Society of London", with Lord Brouncker serving as the first president. A second royal charter was signed on 23 April 1663, with the king noted as the founder and with the name of "the Royal Society of London for the Improvement of Natural Knowledge"; Robert Hooke was appointed as Curator of Experiments in November. This initial royal favour has continued and, since then, every monarch has been the patron of the society.
The society's early meetings included experiments performed first by Hooke and then by Denis Papin, who was appointed in 1684. These experiments varied in their subject area, and were both important in some cases and trivial in others. The society also published an English translation of Essays of Natural Experiments Made in the Accademia del Cimento, under the Protection of the Most Serene Prince Leopold of Tuscany in 1684, an Italian book documenting experiments at the Accademia del Cimento. Although meeting at Gresham College, the Society temporarily moved to Arundel House in 1666 after the Great Fire of London, which did not harm Gresham but did lead to its appropriation by the Lord Mayor. The Society returned to Gresham in 1673.
