Gill, Sir David
Sir David Gill (gĬl), 1843–1914, Scottish astronomer, educated at the Univ. of Aberdeen. He made observations of the transits of Venus and Mars and investigated the solar parallax. As astronomer royal (1879–1907) at the Cape of Good Hope, he carried out the geodetic survey of Natal and Cape Colony and organized the geodetic survey of Rhodesia (now Zimbabwe). He was a leader in the use of photography in the preparation of star catalogs. His photographic survey of almost half a million stars in the Southern Hemisphere (with J. C. Kapteyn) is known as The Cape Photographic Durchmusterung for the Equinox 1875 (1896–1900). This work extended Argelander's Bonn Durchmusterung to the South Pole. Gill was knighted in 1900. His writings include his History and Description of the Royal Observatory, Cape of Good Hope (1913).

Encyclopedia.com gives you the ability to cite reference entries and articles according to common styles from the Modern Language Association (MLA), The Chicago Manual of Style, and the American Psychological Association (APA).
Within the “Cite this article” tool, pick a style to see how all available information looks when formatted according to that style. Then, copy and paste the text into your bibliography or works cited list.
Because each style has its own formatting nuances that evolve over time and not all information is available for every reference entry or article, Encyclopedia.com cannot guarantee each citation it generates. Therefore, it’s best to use Encyclopedia.com citations as a starting point before checking the style against your school or publication’s requirements and the most-recent information available at these sites:

- Most online reference entries and articles do not have page numbers. Therefore, that information is unavailable for most Encyclopedia.com content. However, the date of retrieval is often important. Refer to each style’s convention regarding the best way to format page numbers and retrieval dates.
- In addition to the MLA, Chicago, and APA styles, your school, university, publication, or institution may have its own requirements for citations. Therefore, be sure to refer to those guidelines when editing your bibliography or works cited list.
