General contextBall stemmed from a legal and mercantile family in Devon, whose estate however was reportedly split and fortune decreased at the beginning of William Ball's life. It also slightly unclear of he belonged to a group of displaced royalists who met in London, amongst whom were also Seth Ward (FRS 1661) and Christopher Wren (Founder Fellow), or whether he became interested in astronomy through lectures at Gresham College. The level of detail in Ball's first accounts as Treasurer fill in much of the administrative history of the Society and its earliest Fellows. Ball's astronomical observations on a belt around Saturn played an important part in Christopher Wren and Christiaan Huygens' work and theories on a elliptical 'corona' and a solid circular ring.
