The mid-17th century had seen the community of the curious take its first tentative steps towards institutionalization with the establishment of permanent literary and scientific academies in Paris and London under royal patronage. The foundation of the Royal Society in 1662, with its open door, was particularly important in legitimizing the Republic of Letters in England and providing a European center of gravity for the movement. The Royal Society primarily promoted science, which was undertaken by gentlemen of means acting independently. The Royal Society created its charters and established a system of governance. Its most famous leader was Isaac Newton, president from 1703 until his death in 1727. Other notable members include diarist John Evelyn, writer Thomas Sprat, and scientist Robert Hooke, the Society's first curator of experiments. It played an international role to adjudicate scientific findings, and published the journal "Philosophical Transactions" edited by Henry Oldenburg.
