Of all men who have combined both astronomical theory and practice, Bradley is one of the most remarkable. In this respect, we must assign to him the first place in English history; and if we were disposed to add, in that of the world, we are convinced that no country would pretend to offer more than one candidate to dispute his claim. James Bradley[1] was born in March 1692–3, at Sherbourn in Gloucestershire. He was educated at the Grammar School of Northleach, and admitted of Baliol College, Oxford, in March 1710–11, where he proceeded to the degrees of B.A. and M.A. in the years 1714 and 1717 respectively. His mother’s brother was James Pound (deceased 1724), rector of Wanstead in Essex, and known as an observer, particularly by the observations which he furnished to Newton, as described in the Principia. With him Bradley spent much of his younger life, and was his assistant in his astronomical pursuits; and some observations of 1718–19 on double stars are in good accordance with the relative motions which have been since established in the case of those bodies. His tables of Jupiter’s satellites, on which he was employed at the same time, show that he had detected the greater part of the inequalities in their motions which have since been observed.
