From Wikipedia, the free encyclopedia.
Abbé Nicolas-Louis de Lacaille (March 15, 1713 - March 21, 1762) was a French astronomer.
He is noted for his catalogue of nearly 10,000 southern stars, including 42 nebulous objects. This catalogue, called Coelum Australe Stelliferum, was published posthumously in 1763. It introduced 14 new constellations which have since become standard.
