Born June 12, 1843, in Aberdeen, Scotland; died Jan. 24, 1914, in London. Scottish astronomer.
From 1879 to 1907 he was the director of an observatory on the Cape of Good Hope. In 1880 he determined the solar parallax (from his observations of Mars in great opposition made in 1877) and made a photographic study of the southern sky (1885-89), which was used by the Dutch astronomer J. C. Kapteyn in cataloging the stars of the southern sky (1896). With the help of a heliometer Gill measured stellar parallax and observed the transit of Venus across the solar disk (1874); he also directed geodetic work in South America.
