Lacaille, Nicolas Louis de
Nicolas Louis de Lacaille (nēkôlä´ lwē də läkä´yə), 1713–62, French astronomer. As a result of his success in making meridional measurements in France under the patronage of the duke of Bourbon he was elected to the French Academy. He also became professor of mathematics at the Collège Mazarin, where he established an observatory in 1746. He was at the head of an astronomical expedition (1750–54) to the Cape of Good Hope. There he made observations of 10,000 southern stars, recording their positions; made the first measurement of an arc of the meridian of South Africa; and determined the lunar and solar parallax. Among his works are Astronomiae fundamenta (1757), Tables solaires (1758), Coelum australe stelliferum (1763), and Journal historique du voyage fait au cap de Bonne-Esperance (1763).

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.
