George William Hill (aged 76)
American astronomer and mathematician
George William Hill (March 3, 1838 – April 16, 1914) was an American astronomer and mathematician. Working independently and largely in isolation from the wider scientific community, he made major contributions to celestial mechanics and to the theory of ordinary differential equations. The importance of his work was explicitly acknowledged by Henri Poincaré in 1905. In 1909 Hill was awarded the Royal Society’s Copley Medal, “on the ground of his researches in mathematical astronomy”. Today, he is chiefly remembered for the Hill differential equation.

He also became a member of the Royal Society of Edinburghin 1908, and of the scientific academies of Belgium (1909), Norway (1910), Sweden (1913), and the Netherlands (1914). His later years were marked by poor health, and he died in West Nyack in 1914. He never married and had no children.
