Herbert Hall Turner

Born 13 Aug 1861; died 20 Aug 1930 at age 69.English astronomer who pioneered many of the procedures now universally employed in determining stellar positions from astronomical photographs. After serving as chief assistant at the Royal Greenwich Observatory for nine years, he spent most of his career as Savilian professor of astronomy at Oxford University. One of the leaders in the worldwide effort to produce an astrographic chart of the sky, he developed improved methods for obtaining both positions and magnitudes from photographic plates. Most of his later work was in seismology; he compiled and published worldwide earthquake data starting in 1918, and he discovered the existence of deep-focus earthquakes in 1922.
