“Invisible College is the term used for a small community of interacting scholars who often met face-to-face, exchanged ideas and encouraged each other. One group that has been described as a precursor group to the Royal Society of London consisted of a number of natural philosophers around Robert Boyle, such as Christopher Wren.^[2] It has been suggested that other members included prominent figures later closely concerned with the Royal Society;^[3] but several groups preceded the formation of the Royal Society, and who the other members of this one were is still debated by scholars.”
