Johan Ludvig Emil DreyerDied 14 Sep 1926 at age 74 (born 13 Feb 1852).Danish astronomer who compiled the New General Catalogue of Nebulae and Clusters of Stars, (NGC) in 1888. When he became Director of the Armagh Observatory in 1882, financially it was destitute, with no prospect of replacing its aging instruments. Though Dreyer obtained a new 10-inch refractor by Grubb, the lack of funding for an assistant, precluded him from a continuation of traditional positional astronomy. Instead he concentrated on the compilation of observations made earlier. The NGC he listed 7840 objects and in its supplements (1895, 1908) he added a further 5386 objects. It still remains one of the standard reference catalogs. |
