(1866–1938) English mathematician and celestial mechanician who worked mostly in the USA. His major work was on lunar theory, in which he built upon the work of G. W. Hill. The resulting tables of the Moon's motion, completed in 1919, were based on constants derived from analyses by P. H. Cowell of 150 years of observations made from the Royal Observatory at Greenwich, and were accurate to 1”. Brown also worked on gravitational perturbations of other Solar System bodies.
