The Birmingham enthusiasts, including Boulton, Whitehurst, Keir, Darwin, Watt (after his move to Birmingham), potter Josiah Wedgwood and clergyman and chemist Joseph Priestley began to meet informally in the late 1750s. This evolved into a monthly meeting near the full moon, providing light to journey home afterwards, a pattern common for clubs in Britain at the time. The group eventually dubbed itself the "Lunar Society", and following the death of member Dr William Small in 1775, who had informally co-ordinated communication between the members, Boulton took steps to put the Society on a formal footing. They met on Sundays, beginning with dinner at 2 pm, and continuing with discussions until at least 8.
